Wow !!! Im impressed :):):) I didn't expect such a fast reply !!!

Thanks alot Stefan, I will try it right away !!

Andreas, I really like the idea of hiding attrib 1 and attrib2 and fill attrib3 with a script (I guess using elog.exe command line) ?
I play a little with it and I can modify an attribute with the command line but I cant figure how to set the cell style based on the attrib2 and 
replace attrib3 value with attrib1 value... (basicially I need help !!!) do you think you could help me ?
