specifying window dimensions

Hi,

I have a button that opens a new window ... i want to be able to choose the size the window will be.

I think i need to use:

PHP Code:

---

getURL ("javascript:openNewWindow('example.swf','Home','height=800,width=600,toolbar=no,scrollbars=yes');"); 


---

but it doesn't work. I am quite new to flash so please don't get mad if i am being a total div. Any help would be great.

Thanks.
