Yes, it did fixed it and it works, thank you very much. But to be honest, I would like to know why that Index doesn't work. I did another implementation before reading the info from the cells, doing cell transactions all the time and it was slow, so I posted my code on code review and I did what they told me, turn off events and automatic calcs, etc. Also they told me to load all the info to arrays because that way would be faster, and that's what I did, and with the fix you suggested it is as slow as my first implementation, so that bugs me a bit. —
