Question : Retrieve value of calculated control on a subform

Here is the setup:
Mainform > Subform1 > Subform2

In the footer section of Subform2, I want to display the value of a calculated control from Subform1.  I thought this would have been straightforward, but evidently not for me.

I often rely on this cheat-sheet for quick reference:
http://www.mvps.org/access/forms/frm0031.htm
but it doesn't seem to be helping me for this problem.

After the form has been completely opened and is idle, I can retrieve the value from the control by using this:
Forms!Mainform!Subform1.Form!myCalculatedControl

but when I try to use this reference in a function, it comes back empty.

What am I doing wrong?  Thank you,

Answer : Retrieve value of calculated control on a subform

Figured it out. I disabled the web proxy but enabled url filtering which required web proxy but doesn't tell you. So when it reboots bang nothing works.
