>Whether I run my form from the command line, Form Designer, run main.prg from Project Mgr or run the compiled executable I get this error. The debugger runs through the code in main.prg, comes to DO FORM, runs through the Init method for the form and comes back to DO FORM in main.prg with this error.

>Does this have anything to do with the fact that I'm not using a menu? Help keeps pointing me to PROMPT and the only connection I can see between PROMPT and DO FORM has to do with initializing a menu. I'd appreciate any help. TIA

Chris,

This error is often seen when you have a list or combobox with a rowsourcetype of fields and you have mistakenly used the alisa name in the rowsource property in more than just the first field reference. When using a rowsourcetype of fields the rowsoucre should look like this;

Alias.Field1,Field2,Field3

and not like this;

alias.field1, alias.field2, alias.field3

If you remove the alias form the additional field names the error will go away.
