kuckovic on "Search price range"

Hi all!

I'm using the theme Realtr from Templatic.
I'm making an estate site, and I wanted to know if anyone could help me - here's my problem:

Problem:

In the right sidebar, I have a pricerange option, called "Pris Niveau" - it works fine as it is, but it has to many options.

My vision:

Instead of one drop-down with 30 options, I would like to have 2 textfields, so that the customers can enter the minimum and maximum pricerange - I just can't make it work! Can you guys help me? please!

Code-snippet

<label><?php echo SEARCH_PRICE_RANGE_TEXT; ?> : </label>
          <select name="srch_price" id="srch_price" onchange="" class="fl select">
            <option value=""><?php echo SELECT_ALL_PRICE_TEXT; ?> <?php _e("in","templatic");?> <?php echo get_currency_sym();?> </option>
            <?php echo get_price_range_dl($_REQUEST['srch_price']);?>
          </select>

Please!
I really nees your help...
