is that $gmev being created automatically? if so you are
using register_globals - which is one step in the direction of the
dark side - for the love of <insert preferred god/icon/hero/etc> use
the element in the $_POST superglobal array instead i.e.
$_POST['gmev']

it wants an array - your not giving it an array.

how do you think it should be resolved? what about checking the variable
before blindly using it - time to find a way to check if a var is an array
(or even exists in the scope of the current code) ... there is a function
that does this - it's name is so selfevident that I'm not even going to name it
- seek and you shall find.
