show a text box when an option is selected from a dropdown

I have the following dropdown list box:

          <select name="DDLConditional1" size="1">
                <option selected="selected">is equal to</option>
                <option>begins with</option>
                <option onclick="ShowBetween();">is between</option>
                <option>is not equal to</option>
                <option>is greater than</option>
                <option>is less than</option>
            </select>
I want to show() a textbox and a label based on someone selecting the "is between" option of the dropdown list.
I have multiples of these dropdowns and all of them will have to do the same thing. In other words I have
DDLConditional1 2 3 4... infinite. I've already been able to make the button work that appends new conditionals.
