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

Ed

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

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

eg.

Before ("jim@aol.com" ; "@" ; 1; 0 )
= jim

Before ("jim@aol.com"; "@" ; 1; 1)
= jim@

Thanks. This is helpful. How can script be modified to select text, starting from left, of a string up to the first “(”, when there are multiple “(” 's in the text? eg

typical field:
Actinomycin (Dactinomycin, Antibiotic)(Control Peptide)

result required:
Actinomycin
