Patrick I don't use WOW so I can't confirm anything But I think (and I read that before) WOW formulas are close MS formulas My experience in formulas is limited, I read,try to understand and test,make mistakes, correct and test again,I am far the Graal, I don't run too much after it, many SI members have done a fantastic job before, and open my eyes. Just read the post of Richard ,Claud, Andy , Paul , Brookelise, Dave , and many others....... Thanks to them for all their work and their precious help Michel G |
