Hi xld,

I hope you didn't missinterpret me. My mother tongue isn't English. I didn't mean to call you stupid or anything like that.

I am working with an array of Ranges. It's just I didn't show the code where their content is loaded.

Your tip answers the first q?estion. It's actually like building an SQL statement on a string. Should have thought about that before.

But the second issue is still unanswered. I'll try again.
I want column A to be the sum of column B and C.
And I want that to be dynamic (with a formula), and I'd rather not to have to run a loop (lazy, yes but who isn't).
