EpiCombo problem: cannot find columm name

Hi All,

I have ran into a problem when trying to add an EpiCombo control to
the job Entry form. the idea was to add a control that reads from
the SalesRep BO and writes the SalesRepCode the a UD field in the
JobHead Table.

when I ran that customization I got the following error:

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** Exception Text **************
System.IndexOutOfRangeException: Cannot find column SalesRepCode.

here are the settings I used:
EpiBoName: SalesRep
[0] SalesRepCode
[1] Name
EpiDataSetMode: ListDataSet
EpiSort: none
EpiTableName: SalesRep
SearchFilter: none
ValueMember: SalesRepCode

the rest of the setting is pretty standard.

does someone have any idea what may have gone wrong?
