check text input

[janjansssen]

Hi,

I want to be able to hardcode which numbers (only numbers) can be put into a textbox. When I enter nothing, I get a warning, so now I want to expand the check the system is performing: not just checking if there is a text entered in the checkbox, but also what text. Where can I find the code to expand?

thanks!

JAN

Found it! It's in functions_lookups.php. It's this function:
function zen_get_attributes_valid

Just above return $check_valid; in this function I've put:

if ($value > 6000) {
$check_valid = false;
}
