Filtering by multiple selections at a time gets a lot more complex. Now you'll have to pull the selected offices into a local collection and do a Search (rather than a Filter) to see if a record is 'in' the collection.
FYI, you can make more than one post the solution if you wish. I think @Pstork1 deserves credit for at least 50% of the problem solving here
Actually, I was hoping you could show me what happens when you type up to this point in the function and see what the automcomplete suggests
Distinct('Apprentice List','Base Office'.
I've just created a collection in my combo box as earlier suggested.
If you could help me with one last thing that would be golden!
Currently if no items are selected, the gallery returns blank. Do you know a fix to this?
