running balance using split cells
 

Need to create a Spreadsheet in which I can weekly post a score and then show
the running balance in the same cell so as to keep a condensed report, ie Wk
1: 4/4; Wk 2: 6/10; Wk 3: 7/21; Wk 4: 12/33etc. Top number is weekly
score/bottom number is running balance.

Can this be done with Excel and if so, how.

Thanks much..
