Total From Subform

[jlo]

I have a main form frmJobIn that is a continuous form. A button then takes
you to another form frmJobProcessingSub that is a continous form.

I need a running total that is on the subform to appear on the main form.
The field is called lngVolRec.

I know how to do this for a single form but I cannot get it using a
continuous form. All I get is Name?

Do I have to reference the cmdCommand button that takes me to the subform?
Thanks.
