Thanks so much for the videos they are the best I found and have implemented them. Do you have any others or are you available to tutor? Thanks so much.
Excuse me please and I hope I can explain what I want to make, and you can understand me easily, I need to make a formula for example A and B (A*B) and I want to make (C*A) the column A is about 135 cells, so I need to make( D, E,........*A) everytime I insert another column, A is the basic column so i need when i insert a new column i need to make it easy, instead of making 135 cells everytime. I hope you understand my request and waiting for the reply, thank you
