Type(?)

[Stiletto]

In what case can i use the Type statment and how can i use it?
I have 3 strings that i need a function to search in a string...
Can i put them under Type? like this:

Public Type Tags
    ert1 As String
    ert2 As String
    PNM As String
End Type
Dim Tag as Tags

I'm not sure, but i think this code declairs a var called Tag as Tags (value options are the ert1, ert2, PNM)
Is that right?
