Why now the error condition always is triggered, hm. Replace in IF: TYPE(w)≠4 by type(w)≠ DOM_LIST then this is gone and your example provides about approx 804.57.

ok with DOM_LIST!
but my example is wrong, I must try another Smile

It's correct this: sfint([x,-y,1],[u,v,u*v],[-1,1],[-1,1]) -> 4
Some examples I tried had integral bounds in polar form, so they wasn't right, sorry...

Ok, your program handles also Flux integral!
