I recently started a new job so am a bit busy and may not reply quickly. Sorry - it's not personal - I will reply eventually.
If your problem is solved, please go to 'Thread Tools' above your first post and 'Mark this Thread as Solved'.
If you use commas as your decimal separator (1,23 instead of 1.23) then please replace commas with semi-colons in your formulae.
You don't need to give me rep if I helped, but a thank-you is nice.
