Hello - I've got a sub called addprefstocombo:

Public Sub addprefstocombo()
Dim alpayment As ArrayList = New ArrayList()
Dim s As String

'Load payment options into an array
alpayment = readtextfile("payment.ini")

'Clear out the combobox
Me.cboPayment.Items.Clear()

'Add them
For Each s In alpayment
Me.cboPayment.Items.Add(s)
Next

End Sub

This sub works perfectly when used inside its own form, but doesn't work (and completes without errors) when called from outside its form. I've tried saying:

Dim frm as New frmData
frm.addprefstocombo()

When calling it from another form but this doesn't work. It just completes, doesn't break, show errors, it just simply doesn't work. How do I call another form's subroutine? Thanks!
