Forms :: Filter Second Form Based On Text Box In First Form

I have a button that opens a second form and filters that form based on a text box on the first form(which remains open). the problem is that it does not filter the second form unless the second form is already loaded for some reason.

For example if i click on the button it opens the form Unfiltered then i go back to the previous form without closing the first form, click the button again and it is then filtered .

I attached the screen shot of the macro for the button and there are no other events on the second form.
