it seems that embed url is not working but pi_iframe is working

[askme]

I tried lot to integrate my Guestbook and CMSMadeSimple, after trial and error I came to the conclusion that embed url is not working fine. I tried pi_iframe it is working fine. check my site www.erealmedia.com, but still it seems some problem like size of frame. I want all space of my page should be covered up.
THanks all
