Hello!

Thanks for Your help.
Now I want to show you why I need this, it´s really an exceptional application of Moi.

We're woodworkers.
In order to reduce the chaos of our wood store, each access and consumption of wood stacks is represented by cubes, which correspond in volume to the stock level. When selecting a type of wood, wood thickness, the storage location and the quantity of storage can be determined.
The condition is that access and consumption are always well updated...
Hope it works.

The pictures show the procedure for volume determination.
Thanks also to Max Smirnov, without him this would not be possible ...

Franz
