Are you sure you are doing your maths right? I've just tried it and I had 26.34 in the bank previously and I deposited 475.08 and now I have a grand total of 501.42 which is the sum of 26.34 added to 475.08.
26.34 + 475.08 = 501.42
Now, I had to use Openoffice Calc to store the data prior to the transaction so that I made sure I got the calculation right (we are talking big numbers after all) and as a secondary body to check that the servers maths functions are indeed functioning, which it looks like they are. I also inputted the final figure back into calc and back calculated and the figure still matched my original 2 figures. I have no more money left now so can't try again, and I don't trust the bank to give me the right amount if I withdraw so that'll have to be that
