Hello programmers, got a small problem here as you see i want to add a records on the database(same college, same code but different in centers).So when I click submit button 2 records are saved in my database
EX.

i put text on textboxes           Hidden variables of centers
college = wew                     123
code = wew                        456
centers = (based on hidden variables)
SUBMIT

And when I look on the database
College                 Code               Center
wew                     wew                123
wew                     wew                456

thats what i want, but got a problem. When I hit submit button an error occurs
