I have the following form that is ignoring the onChange event for Bonita Springs when it is selected...what am I doing wrong?

<form style="margin:0px;" action="/lee-county/residential?frame=RESI" method="post">
<table width="100%" border="0" cellspacing="0" cellpadding="3">
    <tr>
      <td><div style="padding-bottom:4px;">City: <select name="search_city">
        <option value="Alva">Alva</option>
        <option value="Bonita Springs" onChange="this.form.action='?frame=RESI&base=frames-collier';" >Bonita Springs</option>  
      </select></div>                   
<input type="image" id="WADbSearch1" name="WADbSearch1" src="/images/search.png" value="Submit">
		</form>                                                            
                        </td>
    </tr>
  </table>	
</form>

onchange should not be placed in the value but in the select

<form style="margin:0px;" action="/lee-county/residential?frame=RESI" method="post">
<table width="100%" border="0" cellspacing="0" cellpadding="3">
    <tr>
      <td><div style="padding-bottom:4px;">City: <select name="search_city">
        <option value="Alva">Alva</option>
        <option value="Bonita Springs" onChange="this.form.action='?frame=RESI&base=frames-collier';" >Bonita Springs</option>  
      </select></div>                   
<input type="image" id="WADbSearch1" name="WADbSearch1" src="/images/search.png" value="Submit">
		</form>                                                            
                        </td>
    </tr>

But I need the action to change based on the option chosen from the select, how do I do this?

Specifically, the <option will have diffrent onChange like this sample:

<form style="margin:0px;" action="/lee-county/residential?frame=RESI" method="post">
<table width="100%" border="0" cellspacing="0" cellpadding="3">
    <tr>
      <td><div style="padding-bottom:4px;">City: <select name="search_city">
        <option value="Alva">Alva</option>
        <option value="Bonita Springs" onChange="this.form.action='?frame=RESI&base=frames-collier';" >Bonita Springs</option>  
        <option value="Another" onChange="this.form.action='?frame=LOTL&base=frames-sanibel';" >Another</option>  
      </select></div>                   
<input type="image" id="WADbSearch1" name="WADbSearch1" src="/images/search.png" value="Submit">
		</form>                                                            
                        </td>
    </tr>
  </table>	
</form>

you can use the if statement

        onChange="if(this.options[1].selected) alert('Hai selezionato il secondo'); else if(this.options[2].selected) alert('Hai selezionato il terzo') ">
