Maths formula wont work please help...
Never really used Excel, so don't know what i'm doing but this > =A28/[ln(A2/0.05)/A30]+(1/20*A31*A2) equation wont work for some reason. Please help...
What is "ln" in your formula?
I guess ln() is natural logarithm. Question is in parentheses. Perhaps the idea was
=A28/LN(A2/0.05)/A30+(1/20*A31*A2)
, perhaps something else
