%%F:=SUM(_F1_)%% does not show in the browser

hello, I am new to Dataform, but I am hoping to use it to achieve almost exactly the same goal that was mentioned by Dave in this post: https://moodle.org/mod/forum/discuss.php?d=392992

I noticed that Dave eventually hired someone to write javascripts to achieve that goal, but I also noticed that in an earlier discussion, Itamar had provided a solution here: https://moodle.org/mod/forum/discuss.php?d=255817

So here is what I have in the design view


In browser view with a test account, I can see the service hours, but not the total in the header:

You can see that the total number of hours which should appear in the header under "Total Service Hours" does not show up at all. 


Did I do something wrong with the formula of "%%F:=SUM(_F1_)%%" ?Can someone help me out here? 

Or should I just move forward to use javascript?
