Taking in params for Mann-Witney's test

#1
Hi guys

I've got stuck with getting Mann-Witney's test params into the analysis dialog options for my svb-program. As I make macro using STATISTICA's 'Create macro' item it gives strange code like:
.CodeForGroup1 = "Multiple"
.CodeForGroup2 = """62c1"""
Are they just codes like "101" and "102" that correspond to text values "Multiple" and
"62c1" or (string) text values as is ? I've tried both but it raises Type mismatch or Wrong group code errors. Please help!
