Facebook email submit iFrame

Hey,
how can I add an email submit offer from Peerfly into a facebook fanpage as an iFrame??

no you can't

must redirect to LP first

iframe ---> LP ----> affiliate link

Hmm ok. But I was able to creat an facebook app with an iframe of the offer but when I try to creat a page tab of this app into my fanpage I always get an error.
And I can't make an iframe of my LP into Facebook because my Webspace doesn't support https and my budget is a bit low this month so I cant't upgrade
