Using the String_Spit action for the first time and it did not work exactly like the Text.String_Spit  action that it is based on.  The Reactive Utils.String_Spit returned an array were the Current & CurrentRowNumber attributes pointed to the last string in the array.  The Text.String_Spit (and every action that returns an array/list that I can think of) returns the array with the Current & CurrentRowNumber attributes pointing to the first item in the array.
