Lotus notes: Hide when formula is true

Lotus notes: Hide when formula is true

I have a view called "vwTest" which have one column and lists 3 docs:
John Mcoy
Peter Pap
Ashley Young
I have a picture with a default hotspot on which I typed the following at
the Hide when formula:
view := "vwTest";
nume := @Name([CN];@UserName);
@If(@IsMember(nume;_view);@False;@True)
The user is John Mcoy. But the picture is hidden. Why? Thanks!
