[ms office - 2010] Excel - Office 2010 - Not updating data totals on some PCs

[DLW13]

Hi,

 

We have recently started to deploy Office 2010 in sections across our school.

 

We have only had 1 fault reported so far and that's with data links within Excel.

 

Workbook 1, totals up the number of marks for each subject, Workbook 2 contains formula to insert the totals from Workbook 1. When updating the totals in Workbook 1 the formula totals will not update on some of the PCs but it will on others.

 

Is there some sort of setting that may be preventing this from happening?

 

Both documents are saved on a network drive
