iframe with tweak dynamic page

[j-c]

Hi,

I have an iframe in a page ( http://www.registratie-domeinnaam-we....be/bestel.htm )
This is a form that has different steps.
Can i use the dynamic page tweak, so that my page expands automaticaly with the page in iframe?

Thanks in advance,

J-C

Or is there a way to do it with php?
