[Jos68]

Hello everyone,

I need some help. I have tried to make a Macro, but it doesn't work as I want. I have put A link to the file below this message.
What i wish is, when I press on the "A" box, the A column stay note filled whith black, and the other column (C5 to F14) are filled whith black. When I press again "A" the spreadsheet reset.
When I press A and B, the column A and B stay note filled whith black, and the other column (D5 to F14). When I press C and D, the column C and D stay note filled whith black, and the other column (B5 to C14 and E5 to F14).

I hope that you have understand my post (Sorry i'm French)

Thank you
