Set you RightArm as an auto enter calculation and auto enter the LeftArm set it to do not replace value if any. You could do the same for the leftarm except set the autoenter as the RightArm.
this would let you enter either arm as the initial value and change the other if needed without replacing the first entered value in either field.
Thanks Marc :)
That was simple to do and it worked absolutely wonderfully!
(By the way, I tried doing it for both, just incase someone decides to enter Rightarm first instead of LeftArm. But that did not work. It becomes compulsory to enter a value for each in that case. Its not that important tho)
It should work, I'm not sure why it's not for you.
RightArm = Auto Enter | Calculated value | Specify = LeftArm (Do not replace value of field (if any) checked)
LeftArm = Auto Enter | Calculated value | Specify = RightArm (Do not replace value of field (if any) checked)
I am not sure either. It is not "not working" exactly. It just does not allow modification if I enter it both ways. As long as it works one way though, I am decreasing work for the user, so it is fine. Thank you!
