How to switch from drop down list to radio buttons onchange that recognizes variable

**techie35** · 12-14-2008, 10:39 PM

HI,

I have working code a friend help me with that creates an array and builds a select option (drop down list). Based on the option chosen in the drop list three images change. This basically picking a theme for you page:
An Avatar, header image and background image.

The option select works but I want change the drop list to radio buttons.
I am stuck on how set up the "value" in the radio buttons to the array of images that need to be changed based on the button selected.

The javascript is using the prototype framework.

Here are links to sample pages:

Just pass the value to the function changeAvatar(this.value)
