change subform child link

[dbb1970]

Hi

i change subform childlink via selection on combobox in after event using
following code:
Me.Subform.LinkChildFields = "SomeField"
which works fine. but i also have a field on main form which adds together
totals from 2 subforms. after changing childlink the field on the main form
shows #Error, even though the totals on each subform still show amounts. i
use the following code to add together the 2 subform totals:
=IIf([Forms]![MainForm]![Subform].[Form].[RecordsetClone].[RecordCount]>0,nz([Forms]![MainForm]![Subform]![sumtotal],0),0)+IIf([Forms]![MainForm]![Subform1].[Form].[RecordsetClone].[RecordCount]>0,nz([Forms]![MainForm]![Subform1]![sumtotal],0),0)
the same #Error shows when moving to other records in mainform

any thoughts on why this is happening and how to fix?

thanks

Hi, David.

any thoughts on why this is happening and how to fix?

Do you have a relationship established between the "SomeField" and the field
used for the LinkMasterFields Property? If not, attempt to create one --
just for testing purposes. Is the Relationship Type in the Edit
Relationships dialog window "Indeterminate"? It should be one-to-many or
one-to-one.

Are you using Access 2003? Access 2003 subforms have some bugs that require
that the linked fields be bound to controls on the form and subform
(LinkMasterFields field on main form and LinkChildFields field on subform).
If you have not designed your form/subform this way, bugs may be interfering.

HTH.
