function call from different window

[simonbuzz]

HEy
I am trying to have a pop up window automatically call a function on its caller page. The function will then change the image on the page which stores the function. so the basic question is how can i call a function called mm_swapp(var1) which is on the caller page which started the popup. I am guessing it could be something simple like window.opener.document.mm_swapp(var1). Is this possible?

Any help would be grately appreciated

using: window.opener.document.mm_swapp(var1); is correct.

Why didn't you just try it?

I trid using the that cde but it didnt call it. I have a page which loads a pop up, then i have on eof the action files run this chucnk of javascript.

<script language="JavaScript">
window.opener.document.MM_swapImage('general','','images/processing.gif',1)
</script>

I know that the MM_swapImage works as i use it constantly. can anyone see why it would not be working. the function is on the page which created the popup.

Thanks, al help appreciated

In your MM_swapImage function put an alert to see what's coming back from the popup window.
