why does put revOpenDatabases() not work?

[william humphrey]

This is what I'm doing in RunRev

on TestPATH



    put empty into fld path

   put empty into fld "database error"

    get the effective filename of this stack

    set the itemdel to slash

    put the (item 1 to -2 of it) & slash & "Recipes.vdb" into dbPath

     put dbPath into fld path

   -- from example stack not from RunRev instructions

     put revOpenDatabase("Valentina3","localhost",dbPath,"sa","sa") into
mDbID

     put mDBID into fld "database error"


end TestPATH


The error is "revdberr,invalid database type"
