What am I doing wrong using Set Null?

I have a raster dataset with values from roughly -24 to 75, but null values are coded as 800.

It seems it should be very simple to just reassign those 800's to NoData using Set Null, but I get a slew of errors.

This is what I'm inputting:

[ATTACH=CONFIG]34413[/ATTACH]

And these are the errors I get:

[ATTACH=CONFIG]34414[/ATTACH]

I apologize if this is something simple or a stupid mistake. I'm not exactly well-versed in GIS.

And of course, if there's an easier way to do what I want to do, I'm all ears.

Thanks!

I suspect the problem is with the raster filename. You have to "." in it, and that may be trowing the error. Try renaming to KFSD_195223_2_4.tif and see if it works.

That cut down on my errors.

Now all I get is two instances of the following:
