Is the following the corect way to use functions? The following works fine,
however When I look at what the experts do they seem to embellish there code
with remarks like "as Double" "as Integer" "as Variant" and wonder if i
should embellish mine in this way, but, I don't really know what it all
means nor do I see the point in it as code seems to run quite happily
without it?

Anyway, here is some code that I have wrote, it works fine and does the job,
but how should it of been done.

PS. I do really appreciate the help that is freely given by others on this
group, it is invaluable, and take this opportunity to wish you all a very
happy xmas!

ActiveSheet.Unprotect

.Offset(0, 2) = "Yes"
.Offset(0, 3) = lB1
.Offset(0, 4) = lB2
End With
end sub

Private Function GetList1Info()
Dim lBox1 As ListBox
Dim temp, i

With lBox1
For i = 1 To .ListCount
If .Selected(i) Then
temp = .List(i)
Exit For

GetList1Info = temp
End Function
