I searched and I found someone say it can be used like this:
IF $'''%TotalList = 200% || %TotalList = 400% || %TotalList = 600%''' = True THEN
But after I try it the flow was just skipped this if line so how I should use the two operands ?
You need to put it all between a single set of % % and use OR instead of ||.
%TotalList = 200 OR TotalList = 400 OR TotalList = 600%
