Multiple forms in a Pocket PC project

I am using Visual Studio.NET 2003. Anyway, I am creating my first multiple form Pocket PC project, and I am having trouble accessing any variables from the first form of the project. I have 4 forms, and each one loads when I press a particular button. Example: Form 1 is the form that automatically loads once I open the program, and once inside this form I press a button and it takes me to Form 2, etc. I use the following method to open each form:

Code:

Dim secondForm As New form2 secondForm.ShowDialog()

Once I'm in the fourth form, I use the following lines to try to access the variables created in the first form:

Code:

Dim frm As form1 Dim x As Int32 x = frm.cuenta ' This is where I get a NullReferenced Exception

The variables in Form 1 are all global and public, but I still can't access them. I have tried using the debugger to get a clearer error message, but for some reason the debugger sometimes fails to load up. Please help.
