Hi,
Is it possible to have [Forms]![frm1]![ctr1] or [Forms]![frm2]![ctr1] in the
criteria of a field query ?

[ctr1] is a number.

thanks.
 
No: not unless *both* forms are open.

The Expression Service will attempt to result the Forms... expression, and
if it doesn't resolve (because the form is not open), you will get the
parameter dialog. I presume that's what you are trying to avoid.

A better solution might be to omit the critieria from the query altogether.
You can then build the filter string as you wish for any form or report.

There's a example of doing that here:

The downloadable example illustrates how to build the filter string for
different field types, combinations, and ranges -- without parameters in the
query.
 
Many thanks for your immediate reply. Yes I was trying to avoid the parameter
dialog. thank you for the links.
best regards.

Another alternative:

Have a separate "Hidden Form" that is always open.

Have each of the two forms move the criteria to the field in the
hidden form

write the query criteria to always use the hidden form criteria.

Advantage:
any query can use those fields as the criteria is necessary.

disadvantage:
will not work for SQL tables since the form is not addressable
however Allen's solution would then need to be used.
