       if checkCD(player) is false:
           cancel event
           stop
       set {homes.%player%.lasthometp} to now

function checkCD(p: player) :: boolean:

           message "You must wait %difference between {@homeCooldown} and {_waited}% before using this command again." to {_p}
           return false
   return true

The variable "shared.%player%.lastdamaged" is set in another script:

on damage of player:
    set {shared.%victim%.lastdamaged} to now

Other Useful Info:

Simply trying to reduce code reproduction in this script. Since I use the cooldown check in two different events it made sense to make a function of it so code would remain consistent if I changed the check.

Addons using (including versions):
SkQuery 3.5.5-Lime
MundoSK 1.7.4

Troubleshooting:

Have you tried searching the docs? Yes
Have you tried searching the forums? Yes
What other methods have you tried to fix it? Reverted my changes to an older copy of the script, went to bed, slept on it, and tried again... same result. Given the catchall "return true" at the end of the function and the fact that the function does not have a "stop" statement in it anywhere I have no idea how this function is returning null.
[doublepost=1486471467,1486469783][/doublepost]Oh god, don't tell me it was that simple...

Functions must be declared higher in the script that when they are used. I assumed since options were preprocessed on script load then functions would be too.
