Form not calculating correctly

We have quite an indepth form set up for an online application.  The form is supposed to total up 35 sections of CEU credits.  See screen shot attached, it works for most of the sections however for "Total number of CEU's in Research" nothing appears.  I went back and compared this field to the others and it looks the same to me. I'm trying to add up all of the research fields.  Can you assist us in figuring out why this isn't totaling?

Thank you!

You seem to have figured it out already. I checked and tested the form, the total is now working. Here's a screenshot:
