Drop down menu creating a list
I have a drop down menu, which contains values from a field in another table
Everything works great when I select one value
What I would like is to be able to select multiple values from the drop down list and have them put in a field separated by a "+"
If the field already contains the value it should simply delete that value from the field
If there is only one value in the field there should be no "+"
Does this make sense?
