Well this form is extremely simple--it was done for a presentation. So I'm going to explain the functionality as if it was a larger form. Basically the ex2_process.cfm validates all the data on via server-side validation rules. If there are any errors, I build a complex variable (a struct or an array) to hold the errors in. If there are errors in the form, instead of processing the form--the main form page is displayed again--which handles displaying of the error messages--and ex2_process.cfm stops processing code. As an added wrinkle, trying signing up for mailing list w/the e-mail address I'm posting from. This is mean to emulate something you can only validate on the server. You'll also notice that no JS error is thrown, that the error is generated by the server--because the page is reloaded. Once you full grasp whats going on, I'll show you code that allows you to improve on that. -Dan ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Upgrade to Adobe ColdFusion MX7 Experience Flex 2 & MX7 integration & create powerful cross-platform RIAs http://www.adobe.com/products/coldfusion/flex2/?sdid=RVJQ Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:275673 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
