[RESOLVED] Add values to combo list box

[vonoventwin]

I have a combo list box that has two values 56 and 58. I want to write the look up like this:

SELECT DISTINCT [FC] FROM tblPSR;

but I want to be able to put new values in on the form also. Like 59 and 60. And when I put a new value I want it to be pulled up in my combo list box. I think my problem is the data isn't in there and it won't allow me to type it in the combo box on the form because it can't find it. How do I fix this??
