JS,

Open the file skin1/modules/Gift_Certificates/giftcert.tpl

Around line 174 you'll see this:

<input type=text name=amount size=10 maxlength=9 value="{$giftcert.amount}">

Replace it with this:

<select name="amount">
  <option value="20"{if $giftcert.amount eq "20"} selected{/if}>$20.00</option>
  <option value="50"{if $giftcert.amount eq "50"} selected{/if}>$50.00</option>
  <option value="100"{if $giftcert.amount eq "100"} selected{/if}>$100.00</option>
</select>

Also, make sure that your minimum amount allowed for gift certificates is set at or below the lowest amount in the drop down box.

Hope that helps
