I have a toolbar that script tool that I created to copy a feature, add some fields and formats them, unsplits the line(its is gps segment lines), adds some more fields, calcs the fields and deletes the old fields. All this is to append it to an existing "Merge_Done"(the Input_Append_Target) feature. The thing is that all of this works awesome, but it appends my feature twice to the so there is two records in the Input_Append_Target feature. I am absolutely not a programmer and don't really know what way to go with this. Help. I have attached the code.
