How to increment an absolute cell reference

[acharletta]

I am trying to increment an absolute cell reference in an Excel spreadsheet column.

What I want to be able to do is increment the absolute cell reference by 7 reslutling in increasing each row number by 7 starting with

='[XOM January 2013 Triage Team Metrics.xlsx]Africa Jan 2013'!$J$5

resulting in the following concecutive rows

='[XOM January 2013 Triage Team Metrics.xlsx]Africa Jan 2013'!$J$12
='[XOM January 2013 Triage Team Metrics.xlsx]Africa Jan 2013'!$J$19
='[XOM January 2013 Triage Team Metrics.xlsx]Africa Jan 2013'!$J$26

etc.

I have multiple rows and columns. Any ideas would be appreciated.
