You do not use the JUMP command, but rather use the logic you show in 
your message. Use the Edit button in the Check screen and type in the if 
statement. You have access to many useful functions as well - in this 
case the ABSolute value function. There are good examples in the help 
file accessible from within EpiData.

  if abs(wt1 - wt2) <= 0.5 then
   goto WT3
