BE,

It is something simple once you realize that the AREA variable is actually an array of areas even if there is only one blob that you are checking. In this case you need to specify the index as in

if area:0 < 4000 then ....

which will fix your particular issue.

Its a subtle point and one that tripped us up a bit too. Just add a ':' and the number next to an array variable to specify a particular value within that array. Note, we use [] to evaluate expressions so something like AREA[0] or AREA(0) does NOT work.

If you check the AREA variable in the Watch_Variables module and scroll to the right you can see the types of all variables. In your case AREA is indeed an array.

Sorry for the confusion!

STeven.
