I have a stateless form "Copy of Test Embed" and report of form "Student" embedded in a page now both the forms have a lookup field targeted to a form "Master" of same field "Subject" and it does filter the report of form "Master" on clicking button of form "Copy of Test Embed", but the problem is that it opens in the new window and not in iframe which i have targeted on.

I have published the form "Copy of Test Embed" and report of form "Student".

HTML snippet of the page as follows:
