Logic Code for post_type=frm_display

Hi,

I’ve got some pages with this structure:
http://www.abc.com/?post_type=frm_display&p=4464&entry=174

and I can’t find the logic code for this…

I’ve tried these:

• is_post_type(‘frm_display’)
• is_post_type()
• if (is_single() && is_post_type(‘frm_display’)
• is_custom_post_type(‘frm_display’)
• global $post; return (is_single() && ($post->post_type = ‘frm_display’)

but it won’t work. Any ideas, how I could catch this?
