Incorrect calculations

It been a few years since I've used Excel properly so I'm a bit rusty at it. I'm currently having problems with some calculations for a project I've been given from work regarding percentages.

As can be seen from the attachment, the sheet calculates the departments participation by looking at what the department has took in relation to the whole company. The problem that I'm having is then using that percent figure to find out the target (8.04% of £1,140,763.98) as to my calculations
cell D11 should be £9,717.42 rather then £91,713.66

Here is the formula I'm using with the participation field formatted to percentage.

=SUM(C8*B11)

Any ideas as to where I'm going wrong?
