Read Multi value fields by Scott A @ 12/25/2016
Hey everyone, and Merry Christmas.

So I have brought some pretty obscure problems, but they are a lot of fun at times. Solving them makes Access infinitely more enjoyable.

One thing I've noticed, is there are a lot of computer people out there that are really unhappy people. Not the case Here!

So Problem:
I have a form that contains related  information from 2 tables. There is a combo box that has a custom Not In List editor that I found on the net somewhere, and another combobox that is a multi-value field. The problem is if I add a new value to the NIL field, the multi-value field will update properly.

Unfortunately, if I use an existing value in the NIL field, it wont. I can get the multi value field to drop down, and select the proper values. But I cannot seem to get it to save to the table, and if the dropdown closes, then it loses the values it contained.

Only thing I can figure, is that there is something else on the form that is remaining in the dirty state. I don't know what it is.

Please dont say "dont use multiple value fields" This will be used later for searching, and I want it that way.

Is it not a required field in your Table that you aren't setting?
Have you got it set to No Duplicates?

Read Multi Value Fields Their Queries by Alex @ 7/14/2015
This question has also been submitted to customer support.

Not sure if multi-value fields are the way to go here, but I'm at my wit's end.

I want to create a form where a user can select from a group of choices (all that apply, just one, or a few). Based upon the selections a report would generate with the results.

For example, I have a hospital with multiple wards in it. Each ward has its own set of employees that I'm keeping track of their training. I want to be able to select as many, or as few, of the wards & have a report listing all of the employees & their training due dates, etc. Please help!

Reply from Alex Hedley:

You could pass these values to an IN Clause in your SQL Statement.

FROM table
WHERE x = y AND x = z

FROM table
WHERE x IN (y, z)
