Filtering With 2 Combo Boxes And Then Populating Text/memo Fields

I have two questions.
I have a form with 2 combo boxes. The first pulls from a simple list. Once you make a choice, the second combo box is then filtered by the first. This works correct, except that once a choice is made in the first, the filter is locked. If you change the first combo box's value a second time it does not effect the second box. The query that I am using for the second combo box has two columns that pull the first 50 characters of a pair of memo fields. Quote: SELECT MSSS.SS_ID, Left([Application_Name],50) AS Expr1, Left([Description],50) AS Expr2, MSSS.Site_Code
FROM MSSS
WHERE (((MSSS.Site_Code)=[Forms]![Edit or Delete Requests]![Combo6])); These fields are then used to populate 2 text fields using an event procedure. Quote: Private Sub Combo10_AfterUpdate()
' Display Partial Application Name and Description based on choice
Me!txtApplication_Name = Me!Combo10.Column(1)
Me!txtDescription = Me!Combo10.Column(2)
End Sub This is working fine, but it starts the next problem.

I need to change the form to include the entire memo field into a text box. I was using the columns of the second combo box to fill them in. Since the combo box is limited to only 50 characters, i could only grab part of it. I am guessing there is a much better way to accomplish what I need, but I am too inexperienced with forms and vb to come up with it. Below are the fields I need from table MSSS
Business_Name
Application_Name
Description
Acronym
Level_1_Support
Level_2_Support
Escalation_process
Troubleshooting
Priority
Links
Modified
Disabled

Thanks in advance to any help!
