Lua :attempt to compare boolean with number?

[Trader]

What does this error mean?

 

[Cykotitan]

booleans are true and false
numbers are... numbers

this error occurs when the script is trying to compare those 2, for example:

if true > 6 then

or

 if 200 <= false

you get the idea.

How do I fix this?
I get an error on line 39 of my script which is this

if getPlayerStorageValue(deathList[killer],kills) < 1 then

It's part of ctf_death script which I can't get to work, when they die by the opposite team, they go to the temple and I want them to go the their team side.
But, when I use the command /attr health 99999999999999 on the player, they go to the right place but they keeping going to it over and over because they have 0 health constantly.
