hi, i have some links at the top of my page that are supposed to have dropdowns all with different links. the problem is, as i have coded it, (i thought correctly) the menu is messed up and doesnt work right. any help greatly appreciated because i thought this menu would work with just a few tweaks. " meet the staff"(menu1) is supposed to start with "specialists", and forms and instructions. (menu2) is supposed to start with Medical HX./..." thanks. derek

here is the page im talking about

http://derekvanderven.com/doctors_columbia/home.html

here is the css for the menu


<head>
<style type="text/css">
.style2 {
font-size: 13px
}
</style>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />


<style type="text/css">

#dropmenudiv{
position:absolute;
border:1px solid black;
border-bottom-width: 0;
font:normal 12px Verdana;
line-height:18px;
z-index:100;


}

#dropmenudiv a{
width: 100%;
display: block;
text-indent: 3px;
border-bottom: 1px solid black;
padding: 1px 0;
text-decoration: none;
font-weight: bold;
background-color: #517e86; /*makes background color of dropdown blue*/
}

#dropmenudiv a:hover{ /*hover background color*/
background-color: #000000; /* makes hover color black*/
}

a:link {color: #ffffff;}
a:visited {color: #ffffff;}
a:hover {color: #ffffff;}
a:active {color: #ffffff;}

</style>

i finally figured it out after an hour. i was typing in "menu1" instead of "menu2". here is the corrected code.

derek




var menu1=new Array()
menu1[0]='<a href="meet_the_staff.html#specialists">Specialists</a>'
menu1[1]='<a href="meet_the_staff.html#endodontist">Endodontist</a>'
menu1[2]='<a href="meet_the_staff.html#periodontist">Periodontist</a>'
menu1[3]='<a href="meet_the_staff.html#ceramist">Ceramist/Dental Technician</a>'
menu1[4]='<a href="meet_the_staff.html#hygiene">Dental Hygiene/ Preventative Dentistry Staff</a>'
menu1[5]='<a href="meet_the_staff.html#assistants">Dental Assistants</a>'
menu1[6]='<a href="meet_the_staff.html#reception">Reception/Front Desk Staff</a>'

//Contents for menu 2, and so on
var menu2=new Array()
menu2[0]='<a href="forms_instructions.html#forms">Medical Hx/Registration Form</a>'
menu2[1]='<a href="meet_the_staff.html#">Post-Periodontal Surgery Instructions</a>'
menu2[2]='<a href="meet_the_staff.html#">Post-Extraction Instructions</a>'
menu2[3]='<a href="meet_the_staff.html#">Post Root Canal Instructions</a>'
