Two userforms - calling a userform method from another userform

[RawlinsCross]

So I have two userforms. I kind of get how to call a subroutine of a userform from another:

1. Ensure you declare the subroutine as Public
2. From Userform2, call the subroutine in Userform1 by using: Call Userform1.NameofSubRoutine

I'm following the progression of the code by stepping through the code. I'm finding that the code doesn't immediately run through Userform1.NameofSubRoutine, but instead first runs through Userform_Initialize of Userform1 before going to NameofSubRoutine of Userform1.

Why question is why does this happen? And is there anything I can do to prevent this from happening?

The Set frm = New SummaryGraph would make a new instance of the first UF. But I don't know why that line it would be called by Userform1.NameOfSubRoutine.
