If you would please try my classifieds you will see that it doesn't on mine.
Are there other files involved in this besides showproduct.php and contact.php? I know it is "supposed" to do as you say, but several posts ago you fixed an error in showproduct.php that was keeping the link from operating correctly.
Couldn't there be another bug keeping my users email from appearing on the contact form? This site is a Postnuke integration, could that affect things?
Please look into this closely, it's very important to me.
