Kenneth,

First off you can't go ignoring syntax errors, just because chosing Ignore allows the code to keep running, it hardly means that it's all of the sudden working or fixed itself. Which specific line gives you the error?

The RowSource can be changed anytime you like. After you do it you must thell the cbo to execute it's Requery() method so it'll reread the RowSource for new values.

>If I move the code to cbo.Init, it's works (using another table), except I don't get the supposed alias, which is dynamically determined by the LPARAMETERS in Init. Does this mean RowSource can't be changed during RunTime? Why the difference with Run Form and EXE?
>Tried setting it in cbo.Init, then setting it again in Form.Init - the error is produced in the latter. Integer-bound cbo's RowSource can't be set in Form.Init!
