Non-existent sortset referenced

[Arkadious]

Background info: I'm trying to fix an issue with the Fused Summoner where it doesn't give the correct base attack bonus for wearing the Eidolon. I haven't even altered the code for cSumFusEid Id yet, and I'm getting an error when compiling.

I've run into an error regarding a script already implemented in Herolab.

When I duplicate the cSumFusEid Id in Herolab and run compile, it gives me this error:

Non-existent sortset 'explicit' referenced by script

When I have a look in the script, completely unaltered, I find the line its referencing:

      ~ build up a description of our Eidolon and include that in our description

        ~full range of sizes in the game

      field[CustDesc].text &= "{b}Evolutions{/b} " & evoltext

      ~ now that we're done building it, append it to our description (the
      ~ printed output also uses this text, but it uses the raw CustDesc field)

      ~ display our current HP as part of our name
      field[livename].text &= " (" & field[trkLeft].value & "/" & field[trkMax].value & " HP)"

What should replace it with to fix the error?
