Active Text Box

**wizgi** · 05-16-2012 06:56 PM

I have the following scenario using a form:

A dropdown with 20 values, with the last being 'other'. When the user selects 'other' they should enter information in an adjacent text box. The text box should be disabled unless 'other' is selected. Is there a way to accomplish this? Of course, I'm open to other ideas as well

Thanks
