I have altered the script to create a roster. Why don't tthe pics pop up when the cursor hovers over the names? The code is below.

Well, the code as pasted into your post has line breaks where none should be. If you are getting an error (yellow triangle bottom left of IE6) and if you double click on it and get a message like:

"object expected"

and a line number around 192. Then that is the problem. When I took out the extraneous line breaks, it worked fine except, of course, the images were missing. If that is your problem, simply put the images in the 'players' directory off of the directory that contains the page.

The code corrections are only needed if it was like that before you pasted it into the message and then only to the function doTooltip:

function doTooltip(evt,num) {
if (!tooltip) return;
if (t1) clearTimeout(t1); if (t2) clearTimeout(t2);
tipOn = true;
// set colors if included in messages array
if (messages[num][2]) var curBgColor = messages[num][2];
else curBgColor = tipBgColor;
if (messages[num][3]) var curFontColor = messages[num][3];
else curFontColor = tipFontColor;
if (ns4) {
var tip = '<table bgcolor="' + tipBorderColor + '" width="' + tipWidth + '" cellspacing="0" cellpadding="' + tipBorderWidth + '" border="0"><tr><td><table bgcolor="' + curBgColor + '" width="100%" cellspacing="0" cellpadding="' + tipPadding + '" border="0"><tr><td>'+ startStr + messages[num][0] + midStr + '<span style="font-family:' + tipFontFamily + '; font-size:' + tipFontSize + '; color:' + curFontColor + ';">' + messages[num][1] + '</span>' + endStr + '</td></tr></table></td></tr></table>';
tooltip.write(tip);
tooltip.close();
} else if (ie4||ie5||ns5) {
var tip = startStr + messages[num][0] + midStr + '<span style="font-family:' + tipFontFamily + '; font-size:' + tipFontSize + '; color:' + curFontColor + ';">' + messages[num][1] + '</span>' + endStr;
tipcss.backgroundColor = curBgColor;
tooltip.innerHTML = tip;
}
if (!tipFollowMouse) positionTip(evt);
else t1=setTimeout("tipcss.visibility='visible'",100);
}A bit of advice for the future, put code tags:




code goes here



around your code in messages here so that it appears as it was when you copied it from your page.
