Hello,  
I’ve just made a new part using my [previous part](https://forum.fritzing.org/t/4050-hex-buffer-non-inverting-dip16/13594) as a template. But I’m getting an error to the effect of “prefix0000 already exists…”

I found the reference in line 2 of the fzp, but I’ve never took much notice of this line before. I swapped it for the part number instead and it loads without error now. Is this the correct way to do it? What is the standard way to name the “module ID” and “referenceFile” on line 2?
