See: http://www.gammon.com.au/scripts/doc.php?function=GetPluginVariable

Note the part about "If you are writing a plugin and want to find a "global" MUSHclient variable value ...".

GetWorldID does not take an argument, it returns the world ID of the current world. Thus GetWorldID("HellMOO") is not meaningful.

If GetVariable is called from within a plugin, the variables for the current plugin are used, not the "global" MUSHclient variables.

Thus, GetVariable returned nil, because it returned the plugin variable, not the world variable, and you tried to add zero to it (for some reason).
