Trying to calculate the wieight on a punch in Microsoft Access (form) in order to calculate the transport charge.
I'm getting an overflow on the following line of code. Can anyone help me overcome this?
w_calc = 3.14159265 * (Me.ShankDiameter / 10) ^ 2 * Me.OverallLength * 7.8 / 10 * 4 * 1000
shankdiameter = 4
overalllength = 80
