All,

A previous question I asked generated a following respons:

Contrary to his statement, ssaqibh's "ARRAY" formula doesn't need to be array-entered to give the correct answer:
=SUM(SUMIFS(Sheet2!$F:$F,Sheet2!$A:$A,{"11020","11030"}))

You could also write it as a SUMIF formula (doesn't need to be array-entered either):
=SUM(SUMIF(Sheet2!$A:$A,{"11020","11030"},Sheet2!$F:$F))

I applied the 1st formual and got my correct response I was shooting for.  I am now curious as to why the expert said this could be entered as an "array" as well, but did not need to, and what an array does for you as opposed to not applying "ctrl,alt,enter", and what is the application to know you need to apply this aspect before you hit the results of the formula.  I guess I'm just wanting a little education on "array formulas".  Are they written different in that they always use the {} symbols in the formula in some way?

Thanks,

Pete
