I have a form that has 1 master page and 3 subforms I want to make page 1 of my subform the master page as currently the master page is blank. How can I make page 1 of my subform the master page?

Can you explain clearly what exactly you are trying to achieve.

You have 3 subforms in one page or you have 3 sibforms in 3 pages?

I understand that you have 1 masterpage.

If you have all the 3 subforms in one page all the subforms will make use of first master page here you have only one master page so there should not be any problem
