I have a form and a sub-form.  On the main form is a field named "txtClasses".

On the sub-form (datasheet view) is a field named "Class".  

When the main form is opened I want the field "txtClasses" to be populated with the UNIQUE values from the subform field "Class" separated by commas and a space.

So using this example of the sub-form...

Classes Example
I would want the field on the main form to read "Football, Baseball, Basketball, Hockey"

How can this be done?

How about building a query on a hidden combobox with the data source "Select Distinct Class From {table}" then run a quick command to iterate through the entries and add commas after them to put into the text box?

Create a query that selects DISTINCT just the Classes field for the ID of the current record.
Select DISTINCT Class
From YourTable
Order by Class
Where PrimaryKey = Forms!yourform!PK;

Then in the current event of the form, open a recordset and loop through it concatenating the values from the Class field.

Pat,

I have the query created and it is giving me the distinct values.  But I don't know how to:

"Then in the current event of the form, open a recordset and loop through it concatenating the values from the Class field. "

What would the code be to do that?

Jeff posted a link to a function that shows you how to do the concatenation.

Yes, Pat
I think Patrick's function is one of the most popular Articles ever published here...

But like you, I sometimes still loop in case I have to check for something at each record...
...and sometimes just because it is fun...
;-)
