Thank you for the reply. I provided a very simplified, striped down version of the model itself. There are thousands of lines of code and there are hundreds of these lines that I need to replace scattered throughout the model, so unfortunately sorting is not an option. Sorry if I was not clear on that in my initial post. Here is a small example of the actual model itself - there are 3 examples of the culvert line that I would need to replace in this snipit (#1. Conn Culvert Barrel=1,Cul1,0, #2. Conn Culvert Barrel=2,Cul1,0, #3. Conn Culvert Barrel=1,Cul2,0). Thanks again for any help:
