Add attributes only once shopper has selected another attribute

[AmandaS]

Hi I am in a dilly of a pickle because I cannot figure out how to solve this.
If a shopper where to selects a certain product from the drop down list of options, then selected colors, size etc...
then if they check another option (eg. wig) I need to be able to add measurements box like this site has
if they where to choose Full Cap (wig) add $125.00, if the shopper selects that option, more required options show up...
is there a way to do this?

Zencart doesn't support dependent attributes at this time.
