Default Set Query Criteria thru Function

Hi,
I'm setting a query criteria thru a function, i.e. V1="RED": SetCriteria(V1)
(setting global variable) and then I use in the Query Criteria another
function to get the global variable i.e. GetCriteria().
It works fine.
Now I want to set a criteria with multiple selections i.e.. V2="BLUE": V3=V1
& " or " & V2
and SetCriteria(V3) but it doesn't work.
I tried with adding (wrap around with) quotes to V1 and V2 but it doesn't
work.
I can make V3 looks like this ""RED" or "BLUE"". or "RED or BLUE"
Any suggestions?
Thanks

global variables... shudder
You could do this with a form-level variable... Why not just save the core
structure of the SQL statement in a querydef and then append the WHERE and
ORDER BY clauses at runtime? Just save the original (unmodified) .SQL
property of the query into a string variable, modify the SQL property and run
the query, and then revert the SQL property back to the saved variable. You
can do all this through your form... should be simple...
