I have created a form but I am struggling to get the formulas as you stated to work (because I don't understand them)

Times.xls

I have decided I will decimalise the times as I enter them as that will make for easyer sums as I am struggling with normal excel formulas without adding new TIME formulas.
Can you take a look at this and you will see what I am trying to do (is is spread over 2 sheets the second sheet will be printed to show just the hours worked for further payroll sums to be worked from by the accountant)
