[SOLVED] Issue with conditionals

Sometimes CC (Minecraft 1.5.1) tells me 1 == 2 and 2 ~= 2. When I run a basic program I have no issues, but with this code it comes up.

This line

	if y == yx then
	  print(y .. ' equals ' .. yx)
	  t.digDown()
	  t.down()
	else
	  print(y .. ' does not equal ' .. yx)
	end

ends up outputting

1 does not equal 2
2 does not equal 2

If I change it to

	if not y == yx then
	  print(y .. ' does not equal ' .. yx)
	  t.digDown()
	  t.down()
	else
	  print(y .. ' equals ' .. yx)
	end

it'll say

1 equals 2
2 equals 2

Use tonumber(read()). Strings aren't numbers.

That works. Love2D didn't do this so I didn't know what to do. Also is input always a string?

Yep.
