How to prevent user from submitting the catalog item

[redth]

When an user selects 'No' for a particular variable, an alert box should be displayed and also they should not be able to submit the form. I need to write a client script for this.

Can you assist me in achieving this?

Best,

Akshitha

Hi,

You can use an onSubmit client script to do this validation.

Here is a small example (UNTESTED)!

function onSubmit() {

        if (g_form.getValue('your_variable') == 'No') {

                  alert('Invalid answer');

                  return false;

        }

}

current is not defined in client scripts. You are trying to respond   too fast.

Right you are. Script corrected.

Up too early and typing too fast!
