create formula. 1 field constant and another field varies by inpu.

[telnettech]

need a formula that takes the 1st number from a field that is inputted by me
and multiplies it by 2nd number i input into another field and then divides
by 100. I dont want extra columns to show. I want to put the number in the
field and when i press "enter" key or "tab" key to move to next cell, that
previous field to calculate and insert the answer into that field. example is
as follows:

A2 82
A3 woulb be "my input"*A2/100= "answer"

need help ASAP


Thanks Brian

A3=(A1*A2)/100

Would that not work? Pending A1 is the field you are putting data into?
