The only way I know of doing what you've indicated below is to use a JavaScript.

You can reference the "parent" or "opener" window by using the "opener" keyword:
opener.document.parentForm.pf1.value = document.childForm.cf1.value;

A good example of how to do this from a JavaScript can be seen here:
