Here is my code segment. I can't figure out what is going wrong, but when I run this, it fails at the buffer stage and returns ERROR 000728: Field (buffer output file) does not exist within table

I figured it out; buffer arguments were in the wrong order, and missing optional args. This fixed my problem.

IanBoddie

Alright, I changed that. Thanks for the tip! Hope this helps

DanPatterson_Retired

Ian, maybe you can format the current version instead of using a screen grab, so people can comment with line number references

IanBoddie

That's just a small mistake in transferring my code over. It's fixed in the current version, but still returning the error, even in the right order

DanPatterson_Retired

param2 input dem raster

execute param2 outbuffer

are they in the correct order?
