I have the display:none problem that may other users have faced. I read all of the topics on this problem, which stated to disable all plugins and look for js errors in the console. I have done this, and was able to remove all js errors except one saying that 'gf_right_half' was undefined.
The form is here: http://preshome2.clickcom.com/make-a-gift-now/
I changed the code back so the errors will currently show, but I can confirm that the form still did not display when those errors were resolved.
