[EpiData-list] IF... THEN LEGAL

Hi all,

I'm trying to combine IF... THEN with LEGAL but somehow I'm having problems with it. Basically, what I want to do is to determine valid values for one variable based on the answer given to another variable. In the example below, the two vars are stateid and countyid: If stateid = 1 then countyid could be 01 or 04; if stateid = 2 then countyid could be 02, 03 or 05.

Example:

countyid IF stateid = 1 THEN LEGAL 01 04 END ENDIF IF stateid = 2 THEN LEGAL 02 03 05 END ENDIF MUSTENTER END
