Hi Emma

Thank you for your question

The first thing to check is whether your system is set for manual or automatic calculation.

Go to Tools-Options and select the calculation tab. At the top check to see if calculation is set to automatic or manual. If the latter, then this will explain your problem, as you have to click the "Calculate Now" button to update the consequences of any changes. If this is the case, setting the option back to automatic will resolve the issue.

If this is not the case, please let me know so I can look at other options

Regards

Stephen
