Hi,

I have the formula to calculate Total Loss.

Ex:
Start Weight = A1
200
Stop Weight = A2
180
Total loss= A1-A2
= 20

My formula is fine. However, As soon as I enter 200 in Start Weight, the
Total Loss shows 200 right away. I would like the Total Loss shows the result
only after I entered value in to the STOP WEIGHT box.

Please help
