I am working on a CMS site whose domain is:

http://www.acmssite.com

They have a sub-domain where they store a form system:

http://www.forms.acmssite.com

I have an iframe on the first that looks at a form in the latter.

I need to run scripts to manipulate the latter from the former and was wondering is this possible?

In order for this to not be restricted by the same origin policy, you will probably need to do this in both the pages:

document.domain = "acmssite.com";
