Hi, I'm new to Drupal and I'd like to know how to do something that should be fairly simple, but can't seem to figure it out.
Suppose I have 5 (integer) dropdowns in a content-type. Say the user select the value "2" from the first one, then "6" from the second one, it should display the sum of the selected values, and the form should not be allowed to be submitted until the sum of all the dropdowns is 10.
Thanks

	# hook_validate()
	# do your validations here
	function example_validate($obj_node)
	{
		$int_one = int_val($obj_node->frm_one);
		$int_two = int_val($obj_node->frm_two);
		$int_total = $int_one + $int_two;

		if ($int_total < 10) {
			form_set_error('frm_one',t('Total should be 10.'));
		}
	}

i hope this is wat u r luking form.....

or may be u can also use jquery to do the calculations and validations...
