Topic a3

I'm having problems with inserting, so I was wondering if you could help me find the problem. I started a new file that used most of my old code that worked but I made a new table, Workers2, that only ask for the id, name, rate for subcell 1, and rate for subcell 2. I wanted to make the training matrix simple to where you just store the values of training to have one row for each worker. The delete function works, but the insert function doesn't work. It just keeps giving me this error message "C:\WebIS\workspace\Work-Cell-Scheduler\TDD\validator.php:88".
