Re: [MS_AccessPros] Re: Dependent combo boxes

It works! Only thing is when I choose a different Car Name it would be nice if the Car Number combo box would go blank instead of staying on the last chosen number. I will now attempt to add the car type and length.

Ah, here's what I found in the Row Source for the cmbCarName combo box:

SELECT tblCars.CarName FROM tblCars ORDER BY tblCars.CarName;

FROM tblCars

ORDER BY tblCars.CarName;

You can't see the second and third line in the Row Source property because of the carriage returns. Open your form in Design View, select the first combo box, click in the Row Source property, then press Shift+F2 to bring up the Zoom box. Delete the second and third lines and click OK.

While you're at it, add the DISTINCT keyword like this:

SELECT DISTINCT tblCars.CarName FROM tblCars ORDER BY tblCars.CarName;

That will list each Car Name only once.

You also have problems with the Column Count and Column Widths properties. Set Column Count to 1 and Column Widths to 1".

You have similar problems with the cmbCarNumber combo box. Change Column Count to 1 and Column Widths to 1".

Finally, there's a blank character in the Control Source of cmbCarNumber. Get rid of that.

Please go to the group website, click on Files and then 2_Assistance Needed, then upload your database for me to look at. Let me know when you've done that.

So, the error must not be from that SQL. Do you have SQL anywhere else in the form? What is the Record Source of the form?

What happens if you click in the Row Source property of the second combo box and then click the Build (…) button next to the property?

Here is the way the combo boxes are set up:

cmbCarName: SELECT tblCars.CarName FROM tblCars ORDER BY tblCars.CarName;

cmbCarNumber: SELECT tblCars.CarNumber FROM tblCars WHERE (((tblCars.CarName)=[Forms]![frmCars]![cmbCarName])) ORDER BY tblCars.CarName; (All on one line.)
I still get a 'characters found after end of SQL statement' dialog box. I created a form using Form Design, and assigned the combo boxes to that form called frmCars.

It looks OK to me, too. It's best to enter the SQL in the Row Source as a single line with no line breaks, sorta like this:

SELECT tblCars.CarNumber FROM tblCars WHERE (((tblCars.CarName)=[Forms]![frmCars]![cmbCarName])) ORDER BY tblCars.CarName;

Be careful if the display in my reply comes back with multiple lines above.

You can also click the Build (…) button next to the Row Source property to open the SQL in the query designer. That should make it easier to spot problems.

Ooops. Got the second SQL wrong. Use this:

SELECT tblCars.CarNumber
FROM tblCars
WHERE (((tblCars.CarName)=[Forms]![frmCars]![cmbCarName]))
ORDER BY tblCars.CarName;

OK, but I think you have it backwards.

The first combo box should be cmbCarName, and its Row Source needs to be:

SELECT tblCars.CarName
FROM tblCars
