    I have a script that is probably pretty simple for anyone who understands javascript and I'd like to customize it with some ASP. I'm guessing arrays is how I would make this happen because of the way it's laid out already. Please correct me if I'm wrong, and help with any code if I'm right... Please.

    Here is the javascript...
    Code:
    <FORM name="isc">
    <table border="0" cellspacing="0" cellpadding="0">
      <tr align="center"> 
        <td nowrap height="11"> &nbsp;
    
    <select name="example" size="1" onChange="redirect(this.options.selectedIndex)">
    <option selected>---Select1-------------</option>
    <option>Webmaster Sites</option>
    <option>News Sites</option>
    </select>
    
    <select name="stage2" size="1" onChange="redirect1(this.options.selectedIndex)">
    <option value=" " selected> </option>
    <option value=" " selected>---Select2--------------</option>
    <option value=" " selected>---Select2--------------</option>
    </select>
    
    <select name="stage3" size="1" onChange="redirect2(this.options.selectedIndex)">
    <option value=" " selected> </option>
    <option value=" " selected>---Select3----------------</option>
    <option value=" " selected>---Select3----------------</option>
    </select>
    
    <script>

    I want the dropdown boxes to populate from a table on a database. Any help would be appreciated.

    Thank you very much

    Hi artsapimp

    To Populate a select box from a database is quite easy all you need to do is the following. Set up your connection and recordset (if you need help with this, please ask) and use the following code

    <SELECT name="MyDropDown">
    <%
    While not myrecordset.EOF
    %>
    <OPTION value="<% = myrecordset("IDcolumn")%>"><% = myrecordset("Descriptioncolumn")%></OPTION>
    <%
    myrecordset.movenext
    Wend
    %>
    </SELECT>

    Hope this helps
