Great advice Dave. Like you idea. I just trying to do one other thing if
anyone can check my syntax. I'm trying to open a window once the user clicks,
plus redirect the page that the user clicks on to open the window. (parent).
I've got ..
<a href="JavaScript:;"
onClick="MM_openBrWindow('http://www.domainname.com/Coupon/install2.cfm?ID=<CFOUTPUT>#ID#</CFOUTPUT>;
','print','width=1,height=1')">Install Now</a>
Could I add a MouseDown to this a href like ... (syntax?)
<a href="JavaScript:;"
onMouseDown="document.location.href="http://www.domainname.com";";
onClick="MM_openBrWindow('http://www.domainname.com/Coupon/install2.cfm?ID=<CFOUTPUT>#ID#</CFOUTPUT>;
','print','width=1,height=1')">Install Now</a>
>> So this install page performs a task that I don't want people
>" + <CFOUTPUT>#ID#</CFOUTPUT>);
