Hopefully a simple answer here. How do I build a message box for my query that will limit the query to item(s) that are inputted in the message box. I know how to do it when there is a finite number of items. But what about if I don't know whether the user wants to limit the query to 1, 2 or 24 items.
Example: Let's say I have a field MONT that takes January, February, etc. as a value.
Now user A want to query for January and July
User B, though, wants to query for February, March, September, and December.
How would you built such CRITERIA? If I knew the user always wants for example 4 months then I can do it otherwise I have no clue
