I have a problem working out the formula for the following.

I get a set of records eg total number of records is 123

I then need to process them in groups of twenty (thats fine, i am dispaying the data in a grid).

What I need to be able to do is jump to the last 3 as I have a button that says "go to end". How do I work out that i need only to display 3 when the "go to end" button is selected

Use the mod function. It return the rest after division:

123 mod 20 = 3
