Need help with GPolyline

Hello,

i've the following code to create points.

var points = [];

function list()
{
GEvent.addListener(map, 'click', function(overlay, point) {
points.push(point);
});
} list();

After that i will draw the lines with this function.

function draw()
{
map.addOverlay(
new GPolyline(points,"#ff0000", 10)
);
}

In Geko it works fine, but in IE i got an error. Any ideas whats wrong?

thx a lot
