This is my Custom Function and I want to edit it


The function and narative describe four variables, yet the sample input and ouput section shows only three variables used.
Three variable, four variables, whichever, I can not get any result with this custom function other that that designated as the "searchString". Why?

Oops... meant


use 0 in 4th param, should work as expected.

believe 4th param gives option to include/exclude the 2nd param in result.


Before ("" ; "@" ; 1; 0 )
= jim

Before (""; "@" ; 1; 1)
= jim@
