Answer 1

Sounds like you aren't referencing the correct object.

Let me example, if you have two forms called MainForm and SecondForm and declare them like this:

Dim myMainForm as New MainForm
Dim mySecondForm as New SecondForm

If you try to access IdSt by doing MainForm.IdSt, that is not the same as myMainForm.IdSt.

So make sure you can access the actual main form object that you set the variable on.
