Drop down menu comparing two DB values, make non caps

I have a drop down menu which values come from a database table, it will display the value based on the value from another table. Problem is that it is case sensitive and I need it to be NOT case sensitive. Here is the code :

-------

<select name="POBCntry" class="bodytext" id="select4" onFocus="mark(this,'#C2D5EB','#000000')" onBlur="mark(this,'#FFFFFF','#000000')">
                    <option value="" <%=(("" == (ContactDetails.Fields.Item("PobCountry").Value))?"SELECTED":"")%>>Please select a Country</option>
                    <%
while (!WorldCountries.EOF) {
%>
                    <option value="<%=(WorldCountries.Fields.Item("country").Value)%>" <%=(((WorldCountries.Fields.Item("country").Value) == ((ContactDetails.Fields.Item("PobCountry").Value)))?"SELECTED":"")%> ><%=(WorldCountries.Fields.Item("country").Value)%></option>
                    <%
  WorldCountries.MoveNext();
}
if (WorldCountries.CursorType > 0) {
  if (!WorldCountries.BOF) WorldCountries.MoveFirst();
} else {
  WorldCountries.Requery();
}
%>
                  </select>

---

Worldcountries.country is the field that is being compared to  contactdetails.pob

I need to make those two not-case sensitive so that if for example worldcountries.country = Mexico and contact.details.pob = MEXiCo   it will still compare them and display the value of worldcountries.country, regardless of how the user entered the name in contactdetails.pob.

I appreciate the help, let me know if you need any more info.
