Hi:

I have a main form which contains a subform. In the subform footer, I have
a text box to calculate the sum of annual cost. When I view the subform,
this works fine, although there is a bit of a lag (maybe 2-3 sec) before the
calculation appears.

I have a textbox in the main form to reference the textbox on the subform.
When I view the main form, I get #Error. Ihave checked all of the field
names, etc. to no avail.

Does anyone have any suggestions?
 
Hi Theresa,

There can be many factors affecting the observed lag time, including--but
not limited to:

1.) Available RAM Memory
2.) CPU and/or bus speed
3.) Hard drive speed
4.) Level of fragmentation of the hard drive
5.) Level of fragmentation with the .mdb file (do a Compact and Repair)
6.) Network speed (if a network separates you from your data) and type (LAN
vs. WAN)
7.) Indexes present
etc.

Check out my Multiuser Applications paper, even if this is a single-user
database, for ideas on how you *might* be able to speed this up.

As for receiving the #Error on your main form, check out this KB article:

Also, I show an example of bringing totals to a main form, from a subform,
in this article:
