Subform not displaying footer total

Attached document shows how I've defined a simple subform with a total in the footer.  I've inserted the subform into a page, but cannot get the grand total to display.  See attached screenshots.  This should be so simple!

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If your subform is in Datasheet view (or a query - which will be displayed as a datasheet), then the Header and Footer do not show. For these to show, you need to use a Continuous  Form view.

You cannot sum a textbox:   =Sumt(txtTotalCost)
You can, however, sum the "Field":  =Sum(TotalCost)

Thanks Experts!  re mx's comment, the subform was a Continuous form already.  I just modified the Grand Total field from Sum(txtTotalCost), to Sum(TotalCost) and works perfectly.  Will remember this for future forms.
