A problem from the quote you get [on the left] of
http://www.poliscarhire.com/ ...
to the mysql repeat region, repeat buttons 2-6 do not work[js] the other 1, 7-16 buttons work properly, why this error ? After all is it, just a repeat [to work all?] ?
Answer and this: a php session var an be reinitialized directly[re-asign a new value to it] or it must first unset ? required the unset ?

form1's submit button work but form2's not work,why[total 16 buttons] ?
