Financial Statements - FSTM 2013

Hi everyone,

I was hoping if I could grab someone's help in a question I'm a little stuck in.
It's the first practice assessment in the 2013 version in Financial statements, task 2(statement of financial position).

For PPE I get £51367 but the answer says £51357

The way I worked it out was:
Cost of PPE = £64,229,000
Servicing costs = £5,000
Acc'd Dep'n = (17,867,000)
Revaluation = £5,000,000
Total = £51,367,000

Can someone tell me where I've missed off please?

Much appreciated
