"compare number with nil" error

[trappedinspacetime]

First of all, I congratulate you on your project. Screenshot looks nifty.
I am running Ubuntu 20.04.4 Mate desktop. I gave it a shot. At first I encountered cpu cores error, my laptop has two cpu cores. I fixed it by deleting the following lines in start.lua after setting cpu cores in settings.lua:

      local cpu3     = cpu_percent(3)
      local cpu4     = cpu_percent(4)

Then I came across

         conky: llua_do_call: function conky_main execution failed: ./abstract.lua:198: attempt to compare number with nil

error.
