It looks like a shapesheet's cell (Width)

This is already a number - it just looks like no number but it is.

If you have a look at the field LocPinX you can see that there's already a formula in it which uses the value of Width (if you take a simple rectangle).

For other cells you can check if these are numbers (to calculate with):

1. insert the section "user defined cells" or a new line in it

2. insert the formula: (the cell you want to calculate with) * 2

3. If the calculation is correct, it's easy

4. If not you have to separate the "numbers" (mid(...)) *1 in order to have NUMBERS.

cheers
