I read the other post on "Request a Quote" button.
I tried to install that Contact module (contact_field 6.x-2.2) but it wouldn't as it is not compatible with Drupal 7.
Here's what i have in mind:
I was thinking to keep "Request a quote" button as is, and link it to the standard contact form as you suggested in the other post. However I wanted to add radio buttons to the contact form to designate the subject requested, with a "QUOTE" button selected by default if the contact form was called from the "REQUEST A QUOTE" button.
Can I do this ?
