page not found with the contact form option ?

I had this problem when trying to use an email field in a view. I found that I had to set the email field in my content type settings to use "Contact form" *and* select contact form as the display in the view. I only found this out after debugging the module code itself; module owner(s), it would be great to build this so it either overrides the default format when you select a different format in a view, or warns you of the mismatch when you try to select it.

I also had this problem. Papayoung made me realize what it was. Under the field settings it was set as invisimail where as the display settings had it as a contact form. Setting both to contact form fixed the problem.

Where and How do I make this change?

I just would like to note, that Papayoung solution works for me just fine in latest dev version. Thanks.

If this helps, all you need to do is change the field on Content type->your content type->Manage Fields->Display Field and see the picture attached.
