*Please refer to the table below*

I have been trying to create a formula to show the percentage increase between the 'without' row and the 'with' row.

I've tried ((without - with)/with) and also included the ABS command to try and solve the negative number issue but the results are less than accurate (see bottom row)

Any help would be most gratefully received

Regards

Glen
