Dynamically add a form field?

[alexjewell]

I have a form that I would like to become dynamic. Here's the form:

http://alexjewell2.com/clients/quinn/apform.php

It's for a client who is an artist to add an art piece. Where I'd like to add a dynamic element is the Medium field: I'd like an input to show up next to the drop-down list if "other" is selected in that list.

Any ideas or resources?

Nevermind - figured it out. I came up with this script:

function mediumOther(theForm){
	show = document.getElementById('other_input');
	if (theForm.medium.value=='Other'){
		show.style.display='inline';}
	else{
		show.style.display='none';}
}

If you have any suggestions, let me know...but it works well. Thanks.
