Hello together,
I want to calculate a sum in subform from a subsubform (sounds
complicated?) but I get an #error but... see below
My database:
I have a main form with members,
each members has in a subform from 0-x projects (in the subform)
each project can have from 0-x subprojects with working days.
What I want:
Now I want to calculate for each project (subform) the total number of
working days.
I calculated in the footer a unbound field to sum (=Sum([txtDays]),
another in the subform which links to this one (=[Project subform].
[Form]![txt_sumDays]).
Problem:
If I only open the subform it calculates the days. If I open the main
form an #error message occures BUT if i click in the subform to the
projects it calculates the days for each row I click?!?!? FURHTER if i
open the subform in the datasheet view the #error message occurs as
well.
Thanks a lot for any suggestions!
Cheers
Andreas
