One way is to put the Number of Loans in a Repeating section but then set
the section properties so that the user cannot Insert or Delete sections.
Then you can have another field or an expression box with the expression:
sum(my:NumberOfLoans).
As you merge the forms, this will total the values in the repeating node.
This can be done in a seperate view so that the repeated (merged) fields
aren't seen.
