Populating a text field in an iFrame

I have been trying to populate a text field within a page in an iframe on a page, i can do it fine normally, but when it is on a different domain it doesnt let me.

Its a security issue but is there a way around it? I have googled it but cant find any solid examples, can anybody help? WOuld really appreciate it, thanks.

there are a few solutions to this, they involve ajax calls. Read this and see if you get any ideas. hxxp://www.ibm.com/developerworks/library/wa-aj-jsonp1/

Thanks for the reply, i appreciate it grazor.

I've had a read now and im at about 25% understanding, will look over it again until i grasp it better, i had found some reading on the internet but this is a little better.

It's a little over my head

If you would be willing to throw together a quick bit of demo code i would HIGHLY appreciate it and +rep and swap software(?) or give you my cookie stuffing script i (semi) designed. Oh and mucho love forever

Ok... after further investigation... i can use prepop email submits so dont need to fill in the email field i can just populate it from a variable in the url.

What i need to do however is submit the form, ive found this link which helps but i get errors when trying to get it to work.

The errors are "Not Acceptable

An appropriate representation of the requested resource /1.php could not be found on this server." - After a search this seems to point to a Mod Security issue but i disabled it and the hosting then doesnt work at all - any suggestions????
