JavaScript/JQuery help

Greetings all you helpful people,
I'm having a little issue with JQuery I was hoping you could either help me with or around.

On the page i have 3 div's
bg1
bg2
bg3

positioned absolute, and on top of each other. With bg3 at the top and bg1 at the bottom.
This was intended to create a transitional image change effect in which i use jquery to fade out the top two images one by one, and then fade them back in.

So the code I have currently is:

var direction = 0; // This is the direction of the fading in or fading out
var current = 3; // this keeps track of which current div is visable

function imgTimer()
{
if (current == 3){
direction = 0; // if current is 3, the top div, then the direction is 0 or down
}
else if (current == 1){
direction = 1; // if current is 1, the botom div, then the direction is 1 or up
}

if (direction == 0){
var iddown = "#bg"+current; //if the direction is down, fade out the current bg
$(iddown).fadeout("0.5"); //problem occurs here
current = current - 1; //set current to the one lower
}else if(direction == 1){
current = current + 1; // if the direction is up, set current to the div above;
idup = "#bg"+current; // fade in the bg div above
$(idup).fadein("0.5"); // problem here also
}
t=setTimeout("imgTimer()",8000); //recalls function after 8 seconds, with any luck
}

The problem occurs on these two lines:
$(iddown).fadeout("0.5");
$(idup).fadein("0.5");

I have tried to implement a variable for what should be:
"#bg3"
or any of the other 2.
unfortunately when the script runs it cannot process the variable as a function parameter.

Firefox gives the error:
Error: $(iddown).fadeout is not a function
Source File: http://localhost/script.js
Line: 107


Is there any way I can make this pass as a string? or a different way I could work around this.
The fading effect is kind of necessary, because I'm not looking for a solid change.
I may have either over complicated this method or preformed some kind of bad code practice, so any and all input is welcome.

Well I found out what was wrong

> $(iddown).fadeout
>> $(iddown).fadeOut

Yup, I left out a cap in the function ¬_¬,
for those reading this in search of answers to their own issues

$("#bg" + current).fadeOut(2000);
This is also acceptable, and parses properly.

Apologies for the thread ^^
