Thanks. Putting the SQL into a string seems to be the best way to do
it but now I have a new problem.

When I change the query GROUP BY field to LAST in VBA the Control
Source name changes from ServiceFrom to LastOfServiceFrom. On the
form I have tried many ways to display both fields like:

=IIf(IsError([LastOfServiceFrom]), [ServiceFrom],[LastOfServiceFrom])
This displays the [LastOfServiceFrom] correctly but gives an #ERROR
when the query is changed to the [ServiceFrom] field.

=IIf(IsError([ServiceFrom]),[LastOfServiceFrom],[ServiceFrom])
This displays the same as the above???? I thought it would be the
opposite but it’s not. Only the [LastOfServiceFrom] displays
correctly. Weird.

How can I get both field names to display correctly in my form when
the Record Source query is changed?
