| 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 “(â€, when there are multiple “(†'s in the text? eg typical field: Actinomycin (Dactinomycin, Antibiotic)(Control Peptide) result required: Actinomycin |
