UDF to evaluate result of concatenate() with additional arg.
I need some help creating a UDF that will evaluate the results of a
string that has been created using concatenate() that includes an
argument to be substituted in the resulting text string.
Concatenate results with the following text string:
(LogCCoef*LN(x))+LogBCoef
LogCCoef and LogBCoef are named excel formulas that return values. The
"x" is the placeholder for the argument that I would also pass to UDF
in the form a cell reference. The UDF would look like:
EvaluateThis(ModelFormula,b12)
Assuming:
ModelFormula (a named formula) is:
=concatenate((LogCCoef*LN(x))+LogBCoef)
LogCCoef (a named formula) returns: -6.35
LogBCoef (a named formula) returns: 55.8
Value in cell b12 is: 400
The UDF would return 17.75 [(-6.35*ln(400))+55.8]
Could someone provide some guidance?
