Loop keeps going?

add into the loop (just before the until)

print( "i = "..i.." width = "..width )

what are the values?

Nevermind I see the issue, change the args lines at the top to be

tonumber( args[ x ] )

where x is the arg number

the problem was you were comparing a number with a string… which will always be false

lol I already did the first bit for debugging and it properly catches the width but i will try that second part and report back ty for the help. :D/>

local var = ( someVar == "true" )

I don't think there is a tobool or toboolean, and googling seems to indicate there isn't… i always just do this

local var = ( someVar == "true" )

function toboolean( str )
  if str ~= "true" or str ~= "false" then
	return nil
  end
  return str == "true"
end

someVar = toboolean( args[1] )

ok how about this… does this make a little more sense?

function toboolean( str )
  if str ~= "true" or str ~= "false" then
	return nil
  end
  return str == "true"
end

then using it

someVar = toboolean( args[1] )
