Passing Value Of Convert To Other Procedures That Are Being Called?

I am running this code it is rather long, but I need to show it all ?

Code:
Public Sub Monday()
Dim mName() As Variant
Dim lName() As Variant
Dim fName As String

Call lower(CStr(mName(q)), fName, CStr(lName(q)))

[Code] .........

How to do is to pass the value of convert to the other procedures that are being called? As you can see I know how to pass variables down to "Sub-routines" but how would I pass the variable up?
