Check the calculation order.
I do not understand? ....
Acrobat does not compute field in a standard order like left to right and top down. It executes the calculation in each field in the order the fields are added to the PDF unless you edit the field calculation order during the form editing process.
Here is a screen shot of a portion of the calculation order for your form:
You are computing the TotDapUsd before any of the ValDapCop.# fields are calculated even though it is the sum of the ValDapCop fields!
You also have a number of fields were you are trying to divide by zero that need to be addressed.
