reset is not required when using foreach. and given that you have probably
not looped that item

you may be getting into trouble because of php's typecasting - try using
fielnames that are strings that do not auto cast to integers (which can be
used as array keys for indexed arrays) e.g. "cb1" instead of "1"

is it? (use print_r() or var_dump() inside the loop to see what is happening)
NOT SO SUBTLE HINT: USE echo, print_r() and var_dump() until either you fingers or
your eyes start to bleed ;-) if you still haven't figured it out by then it's
