I have two code modules, one named "Primary" and the other is "Utils".

'The "Utils" module has the following subroutine:
'-----------------------------------------------
Public Sub Foo (a as Integer, b as Integer)
MsgBox "Nothing here."
End Sub

' The "Primary module has the following subroutine:
'-------------------------------------------------
Public Sub Goo()
Dim x, y as Integer
x = 2
y = 3
Utils.foo x, y ' ByRef argument error here
End Sub


When you run the Goo() subroutine, you get the
"ByRef argument type mismatch". What's wrong here?

'x' isn't (necessarily) an Integer, it's a Variant (unless there's a Deftype
statement somewhere). You have to specify each variable's type to change it
from the default:

Dim x as Integer, y as Integer
