Need Help For a Tiny Program

so i wanted to make a short mineing program but i cant get it to work

local input = read()
fuellevel = turtle.getFuelLevel()

if fuellevel<input
then
print("need refuel")
else
Print("Mineing")
--Function goes here
end

when I test it it says

mine: 5:  attempt to compare sting with
number expected, got string

im doing something wrong but what, please help,

read() outputs a string and turtle.getFuelLevel() outputs a number, the types need to match for you to compare them. Convert the read output to a number by doing this

local input = tonumber(read())

try

local input = read()
fuellevel = turtle.getFuelLevel()

if fuellevel<tonumber(input)
then
print("need refuel")
else
Print("Mineing")
--Function goes here
end
