Lookup Wizard with 2 conditions in Where expression

Hi All,
I have a field that looks up folks in my "roster" table and displays there name to select from.
I added this "Where" statement ("Title = 'ASOM'") to identify these folks by there title and it works, but I need to add a second condition in that "Where" expression.
I added this ("Title = 'ASOM'" OR "Title2 = 'ASOM'") and it doesn't work.
Can you tell how I can get field to list folks who have the same title whether it's in "Title" or "Title2"?
Thanks,
