Hi,Thanks SamT , i will try and revert if its ok with the timing. thanks you for your kind help.P45Cal: Yes you are right the formula shall start on row 60 and not on row 59. Well concerning pirate or not. I cannot tell you as its the administrator who do all in the installation and also my pc has just been bought. So am not in a situation to confirm if this is pirate or no.But still thanks for helping.
