links in iframe dont work?

[Manmade]

I have a page in my webapp, with an iframe that is loading a page with a form in it.

And I can select the select menu, but I cant submit the form, and if I load my own webpage in the iframe, none of the menu links work?

If I test it in the desktop safari it works, but not when testing the webapp on the phone?

Any input really appreciated thanks.
