Makis,
why do you use $HTTP_POST_VARS? Do I miss something?
if you have a form and send it, the vars have the same names as in your
form, will say if your checkbox name="foo" value="someval" will be transmitted,
then in the following page there´s a var named $foo. and the value will be
"someval"
if the box is checked, otherwise there´s no (or NULL or FALSE ???) value in it.
I personally prefer put checkbox vars (if there are several) in an array
f.e. $foo[]
In the following page I just scan the array and if there´s a value in a field
thats fine.
