}
Please kindly advise on this error can be fixed please

Thank you very much

Below is my full javascript program:-

assuming the error is about node.obj.draw() you need to ensure that node & node.obj are the objects you expect. (I guess FireBug Lite will be necessary for this)

Thanks for kind advice, will try.

Do you've any recommendation how the statement below can be modified for it to work with IE8?


this.nodes=(node.obj.draw(0,0,this.getp(node,"widt h","100%"),0,this.getp(node,"bgcolor",0),0,(100 0-this.num),this.getp(node,"div_class",0),s));
}

Please kindly advise

Thank you very much in advance
