Hi,

Here is my situation:

I have three frames: desktopleft, desktopright, desktophead.

Event: Intially desktopleft loads the data.

* Once i click on desktopleft tree structure, desktop right list populates the data(if it has), and the first row will be selected default.

* Once the first row selected the event, i need to load the desktop head with few buttons.

My prob: Getting error like: Object cannot support
enable_buttons function in desktop head page.

this function is called from desktopright frame and before desktophead loads this function is trying to execute and i am getting the error..?

am i clear ..?

Is there a way to know whether the frame load successfully using cliet script..?

Thanks in Advance.

in your code, try breaking the logic down like the following

var obj;
obj = window.frames("desktophead")
if obj==null {
  //error occured, do nothing
}
else {
  enable_buttons():
}

why don't you just call enable_buttons() in the onLoad of the desktophead frame?

you can continue the logic further into your page to some object that you know will be there if page is loaded.  test at each point where you are going another level deeper into the object model and there is a possibility that object is not there.  this will let you trap the error before it happens.
