Hi everyone, I always post on here whenever I'm really stuck - and I'm really stuck again, so I hope someone can help!

I have a list box with certain options in in. My last option at the bottom of the list menu is called "Other".

This works fine, no problems.

What I'd like to happen is for a text box to appear when I select 'Other' (into which I can type my free-text, "Other" category.

So far, I have figured out how to show and hide layers.... but the show/hide behavoiur is, by deafult, applied to the WHOLE list menu - which means the text box is displayed when ANY of the  options are selected...

Does anyone know how to get this to work?

Thanks!

Do you want to make a textbox visible and invisible based on the option selected in the list?
