autocompute or auto calculate

[sleepyheadking]

hi,

can someone help me create an auto pro rata calculator where there are four [4] boxes. first box should be where we could enter the customer's plan [29,39,40 etc.] and it should be divided with what ever i will enter on the second box w/c will be for the number of days in a month [28,29,30,31]. the 3rd box should be where i can enter the number of days the cust. was able to use the service and it needs to be multiplied from box 2. 4th box should be a read only box where the pro rata will be displayed.

so:

[box 1] divided "/" by [box 2] multiplied "*" by [box 3] equals "=" to box four

thanks!!!
