Sorry but I think I was a Little too fast there.

No matter how many there are, it always comes to the same result, 1. If I leave out the COUNTA from the formula, and only use

=INDIRECT(ADDRESS(1,MATCH(FALSE,IF(1:1="",COLUMN(1 :1)),1)+1)&":"&ADDRESS(1,MAX(IF(1:1="",COLUMN(1:1) ),1)))

I can see that it returns the content of the last cell which has content. And then it apparently only Counts that.

hi Jan,

the formula is an array formula to insert with CTRL+Shift+Enter

=COUNTA(INDIRECT(ADDRESS(1,MATCH(FALSE,IF(1:1="",C OLUMN(1:1)),1)+1)&":"&ADDRESS(1,MAX(IF(1:1="",COLU MN(1:1)),1))))
