I need to use VBA to determine the number of arguments passed to an Excel formula. For instance, suppose a cell contains the formula =MyFunc($A$1, "xyz", SUM(1,2,COUNT(C1:C12)), IF(B1>2,1,0)). Then the counter function should return 4. Does VBA contain any built-in functions for this, or does someone have an example of a regular expression that could calculate this?
