Thanks, guys. That's what I figured. While I'm no Python guru, I was in the IT field for 39 years. This isn't the first time I ran into things like this. I will do as you both suggest. I can add a "feature" to the stock file one at a time, and fix the errors as I encounter them. The good news is I have two parallel systems . . . one is my live site:
https://www.ve1dx.net And the other is sending the simulator data to a subdirectory under it. I even have two Davis receivers, each with a data logger and USB interface. I do so because I have this obsession not to let my site go offline (failing power outages.) I always try to have a backup plan and duplicate the hardware if possible. I used to manage Unix servers for up to 2000 clients, and downtime was a no-no! So . . . it looks like I have my work cut out for me. It's something to do during this long, cold, dark winter. One bite (byte?) at a time is the way to go when facing an elephant. - Paul VE1DX On Tuesday, December 29, 2020 at 5:16:36 PM UTC-4 gjr80 wrote: > Hi, > > Short answer is there is no direct way of obtaining the offending line > number in your template file.
