Android Question Problems with GSheetplus Library , the s.Initialize(...

Hi!
I bought GSheetplus and thought it whould work but I get an error-

I tried an example and the error gets on this row:
/../
Dim ClientId As String = "xxxxxpath.apps.googleusercontent.com"
/../
s.Initialize(Me, "gs", ClientId)

But what is "gs" ?

The error text is (parts in Swedish):
B4A Version: 12.80
Parsing code. (0.02s)
Java Version: 14
Building folders structure. (0.01s)
Compiling code. Error
Error compiling program.
Error description: ',' expected.
Fel uppstod vid linje; 35
oauth2.Initialize(Me, "oauth2", myClientID, "https://www.googleapis.com/auth/drive")
Word: )

Please help me!
