Are you sure your middle frame is actually named 'middle'? Ex:
HTML Code:
<frame name="middle" src="middle_page.htm">
If so, do you have more than one frameset? The parent is the frameset immediately above the page in question, if there are frames within frames, you may need to alter the script to:
Code:
function jumpto2(url){
if (buttontarget=="")
window.location=url
else if (buttontarget=="_new")
window.open(url)
else
top[buttontarget].location=url
}
There are many other possibilities. It's hard to say what it is for sure, without seeing your page.
Please post a link to the page on your site that contains the problematic script so we can check it out.
