I am not able to replicate that. I put the number 3 in Inward!D25 and 11.25 in H25 and it shows up as the third value in the Aluminum Tube column on the Stock in Hand sheet. I then placed the value 3 in Outward!D25 and the value 11.11 in H25. That resulted in leaving the values 13.25 and 11.25 in the Stock in Hand sheet. Could you upload a sample of your file showing the issue that you have encountered?
