[LUA][Help]clearPrint fuction

I'm trying to make an argument for my clearPrint fuction, so if you type p in the place of o it will print the string, or if you type w it will write the string. But I can't get it to work. It use to clear the screen but all of a sudden it doesn't anymore ._.

function clearPrint(string, o, x, y)
    if not x or x < 0 then x = 1 end
    if not y or y < 0 then y = 1 end
    term.clear()
    term.setCursorPos(x,y)
    if o == w then
        write(string)
    elseif o == p then
        print(string)
    end
end

put quotes around the the "w", the "o", and the "p", so it knows its a string, if I understand what you mean…

only around "w" and "p". o is a variable

ya, didn't fully look at the code :P/>/>

DERP Can't believe I forgot about that, damn.

function clearPrint(string, o, x, y)
    if not x or x < 0 then x = 1 end
    if not y or y < 0 then y = 1 end
    term.clear()
    term.setCursorPos(x,y)
    if o == "w" then
	    write(string)
    elseif o == "p" then
	    print(string)
    end
end

Now when I use it it clears the string that I have written.

clearPrint("derp", p)

It wouldn't show anything because for something it clears the string? O_o

function clearPrint(s, o, x, y)
    if not x or x < 0 then x = 1 end
    if not y or y < 0 then y = 1 end
    term.clear()
    term.setCursorPos(x,y)
    o(s)
end

Doing this works, but I want the argument to have just 'w' or 'p' not the full words :P/>/> Why?

Try passing it "p" instead of p.
