Showprompt message disappearing on select

[Niranjan-KC]

Hi,
I am trying to make a simple custom validation on a select. The select needs to have a value selected when another textbox is entered otherwise it need not validate. This is my HTML
<select id="selectid" class="validate[funcCall[validateSelect]]"></select>

Here is my method
function validateSelect(field, rules, i, options) { if ($("#textboxid").val().length > 0 && !($(selectid).val() > 0)) $("#selectid").validationEngine('showPrompt', 'Error Message', 'error', 'topRight', true); }

This triggers the validation and the message appears but it disappears immediately. I have not set any fade outs. Appreciate any help.
