How to put a nested IF-statement?

Hi,

I cannot succeed in building a nested IF-statement with ELSE IF's.

IS the config

FACT = TRUE
IF <1> then
ELSE IF <2> then
ELSE IF <3> then
FACT = TRUE
END IF
END IF
END IF

Or without the END-IF's in between?

thnx Marc

For each and only starting IF there should be one END IF:

Thnx Erel!
