[OpenLayers-Users] Removing a layer

[bartvde at osgis.nl]

Probably this is because of the scope of your variable.

If you define var xxxx in a function, it only has a local scope inside of
the function, outside of the function it is not accessible.

Instead, you can define the variable outside of the function with the var
keyword.

var xxxx = null;

function init() {
  xxx = new ......;
}

Best regards,
Bart
