The basic format of an IF statement is:
IF <insert logical test> THEN <some result>
Nested IF statements simply add another IF layer after your logical test:
IF <insert logical test> THEN
IF <insert additional logical test> THEN <some result> END
ELSEIF…. ELSE… END

Using a nested IF, I could write the following calculation for our example:
This calculation results in the following:
