Line graph shows flatline because formulas show 0.00 - HELP!!

Hi all,

I'm trying to create a worksheet which autofills from another worksheet

I also have a line graph attached which I also want to auto fill

However, once the formula is set up it shows a flat line on the graph

formula is as follows

='[Management fee summary2.xls]2013'!G360

can anybody help me?

Apologies to MartinDWilson, who answered the last time I asked ...I had to shelve the plan until now
