Preserved Topic: its me again (Page 1 of 1)

Hi Everybody,
it's me again! I wrote the following script to scroll a background layer..... so please tell me why the direction of the scroll doesn't change... I can't finde the error!

var id;
var direc="";

function Glide() {
if (ie) {
checkdirec();
if (direc="left") {document.all.landscape.style.pixelLeft -= 10;}
else if (direc="right") {document.all.landscape.style.pixelLeft += 10;}
window.clearInterval(id);
id = window.setInterval("Glide()",30);
}
function checkdirec() {
if (ie) {
if (document.all.landscape.style.pixelLeft<=-1800) {direc="right";}
else if (document.all.landscape.style.pixelLeft>=0) {direc="left";}
}}

if (direc="left") should be if(direc=="left") Same with the other if statement.

The equals sign assigns the value on the right to the variable on the left, and then returns the new value of the variable. In this case, it assigns "left" to the variable direc, and then returns the string "left", which, since it's not the empty string or "0", is true.

The double equals compares the two things, and if they're equal, returns true.

THX alot slime!
This forum is so cool.....
Thank you all very much!!

If I have an If statement that looks like this
_________
if (d=="l")
{
if (currentPos >= x)
{
document.all.container.style.pixelLeft -= 10;
}
else document.all.container.style.pixelLeft = x;
}
_______

shouldn't it stop the layer being moved once it equals x?
