I seem to have found another problem with the Tax issue in MS1 which is giving me problems.

I have my Tax set at 17.5% on my website.

If for example a customer buys 6 products from my website worth $8.08 each excluding the Tax, oscommerce will work the Sub-Total as being $56.94 including tax, when it should be $56.96.

Reason for this error is this is how oscommerce calculates the sub-total:

[color=red]$8.08 + Tax = $9.49 x 6 = $56.94[/color]

But it should work it out like this:

[color=green]$8.08 x 6 = $48.48 + Tax = $56.96[/color]

Any ideas how I can fix this error?
