I have three sources set up. It's easy to find out the total number of records for each one.

How can I find out the total number of records in all three combined?

Hello Brad,
Is your question related to the total records of 3 different repeat regions? Please explain a little more detailed what exactly do you need to achieve?

I have three sources.

I can get the number of records in each one individually no problem.

Suppose:

{{NOC1.total}} = 10 records
{{NOC2.total}} = 8 records
{{NOC3.total}} = 2 records

I need to be able to get the total of all three together ...

{{NOC1.total}} + {{NOC2.total}} + {{NOC3.total}} = 20 ...
