When the user enters a quanity in a field on the main form, my program calls a procedure to perform a calculation.  The calculation needs to reference another field on the subform of the main form - this is an unbound field.  This is what I came up with, but I receive an error - 2450 can't find the referenced form fsub_equipment_selected.intTrainTotal

Main Form:  frm_Opportunity_Quote
Sub Form:  fsub_Equipment_Selected
Field on Sub Form:  intTrainTotal (unbound field displays totals on subform)
Calculation:  intNoFin = intNoFin - intTrainTotal

you use this format

Forms!frm_Opportunity_Quote!SUBFORMCONTROLNAME.intTrainTotal

open main form in design view
select/click  the outer edge of the subform control, then hit F4
select the ALL tab, the entry that you will find in the NAME property is the SUBFORMCONTROLNAME, use that in the code above

see this too as reference
Refer to Form and Subform properties and controls

A more dynamic method (without specifically pointing to a static field in a form):
Create a public variable in the DECLARATION SECTION of a code module.

Public glbYourFieldName as string   '--- or integer, or single, whatever data type.

Now, create a fuction to retrieve this value:

Function get_glbYourFieldName() as string '--- or integer, or single, whatever data type.
get_glbYourFieldName = glbYourFieldName
End Function

Now, create a query and in the criteria section - simply enter  "=get_glbYourFieldName()

Now, in the after update event of the textbox, simply assign a value to the public variable glbYourFieldName

glbYourFieldName = "" '-- or 0 if numeric data type
if not isnull(me.txtYourTextBox) then
       glbYourFieldName = me.txtYourText Box
end if

Now, you can run that query FROM ANYWHERE and you will get your expected results.
You can also use this same query from ANY FORM simply by assigning a value to the public variable.

It's a little work (not much) but you can design whole systems around this type of procedure and reuse queries over and over again.
