The problem I have that needs to be fixed is in four different places in the code. The javascript code adds the particular field values from the webpage's table cell, but only produces a whole number, but without the decimal number. For example, if the fields are 10.5, 5.1, 6.3 the resulting number produced by the code currently is 10+5+6=21 but the real answer is 10.5+5.1+6.3=21.9 which is what I need to show on the webpage.

I have a php booking script that will not post to the mysqli database because of the following reasons: 1. Notice: Trying to get property 'num_rows' of non-object... and 2. Fatal error: Uncaught mysqli_sql_exception: Commands out of sync; you can't run this command now in... So, I need these errors fixed and anything else so the bookings can be posted to the server, the reply successful message appears, the green slot turns red that was just posted to and have the ability to select which bookings I want to initially be red or green each month. If you cannot post how much this will cost up front, please do not make a request to be awarded this project. Thank you.

I'm using some pieces of code to calculate an user's time on the site from the time they login to the time they logoff the site, so each time they visit the site and login, their seconds, hours, days, months and years are updated in the dbase from which I can then output the data for those who need to see it. For whatever reason it is not working like I need it to do, so I need a coder to check the code and make the changes to it so it will work for every user and aggregate their data to show how many seconds, minutes, days, months and years they have accumulated on the website.

I have a script I bought and made changes to it to fit what I needed, but in doing so, the script will no longer register, post to the dbase or post back which questions were not answered, so all the results needed to calculate the true quiz percent result will not be correct. So, I need a coder to change the code, so the script will be able to have each unanswered quiz question no matter how many questions are selected by that user for that quiz to be registered in the dbase as unanswered when it is unanswered and in doing so, it will be used to truly determine the correct percentage given the number of right questions, the number of wrong questions and the number of unanswered questions to get the correct percentage and have it posted in the dbase too.

I have a table on the home page that list events, etc. and with it it has a pagination. The pagination allows for the number of events listed to be set and once that number is reached, the next, the 1,2,3,4,5 and the previous links show up. The problem happening is the links show up automatically regardless of what the maximum number of the events listed is set to show before the pagination starts and when I click any of the pagination links it goes to the next page, the table is blank and this doesn't matter if it is the previous 1,2,3,4,5, next page links. So, I need the pagination and the links to work properly.

I have a paypal webpage that shows the payments, donations and revenues transactions processed by paypal.com and at the end of each row or along the row, it shows the money amount or the nets (2 or 3). There are five sections in the code where the amount total needs to go, two sections where the net (3 instances go) and two sections where the net (2 instances go). I need the total row to show at the bottom of the table that will calculate the total and continue to show at the bottom with the total changing as more payments, donations or revenue are added to the table and the number of rows increases accordingly.

I have a php file that enables the user to select Cost Per Hour or Free using the check button. When the Cost Per Hour is checked, an input field opens up, so the user can add the cost: $20.00, etc. Well, I need to add another checkbox for Fee and when clicked, an input field is opens up for me to add the cost. In either case, the Cost Per Hour or the Fee input field for the dollar amount is disabled if not selected.

I have a file that connects to the database using mysqli and I need it to be changed so the query will return all rows of the primary ids that are of a certain type and then list those results so I can then select (checks) and send an email to one or to a few or to all of them at one time.

I have two webpages. One webpage has an email specific to one user along with the email for the organization, club, etc. associated with that user's profile. The second webpage can have one or more emails, which depends on how many user are registered for the session, which could be from 1 to 150 users, and those emails are unique and specific for that particular user.
