See attached.
Click form frmMainBig.

This shows a single customer (tblCustomers) who is buying 3 products (tblQuoteDetails - see the green bits).

Specifically, note the "line value" in green.

Now look at the orange field at the bottom of the subform.
I want the orange to show the sum of the "line values".

i.e. the Orange should show the sum of the green "line value"
I have tried various options but am unsure of my approach.

All help appreciated!  I hope this is clear.

In your subform, frmQuoteDetails, place a text control in the forms footer.

  Call it txtLineTotal.  Set it's controlsource to:


 Now in the main form, set the controlsource for XXSumOrderValue to:

 BTW, the text control in the subform can be hidden.

Slight correct; the text control in the subform footer needs its controlsource to be:
