Hello all. I'm using a character sheet whereby characters can have a varying Max health, represented by Health boxes on the page. At the moment, we have a number field where users input their max health, but there's still the same number of boxes visable on the sheet. I know you can use CSS code to hide certain elements, but i don't know if i can tie this to a field where users enter a number, as opposed to a checkbox.   This is what i have in the HTML for my max health box at the moment:                          <input style="width: 40px" type="number" name="attr_maxhealth" />                      And this is the code for the multi-state Health boxes.     <div align="center" class="sheet-health-box">                              <input type="radio" class="sheet-health-box sheet-no-health" name="attr_health-box9" value="0" />                              <input type="radio" class="sheet-health-box sheet-bashing-health" name="attr_health-box9" value="1" />                              <input type="radio" class="sheet-health-box sheet-lethal-health" name="attr_health-box9" value="2" />                              <input type="radio" class="sheet-health-box sheet-aggravated-health" name="attr_health-box9" value="3" checked="checked"                              />                               <span class="sheet-health-box sheet-no-health"></span>                                <span class="sheet-health-box sheet-bashing-health">&nbsp;∕&nbsp;</span>                              <span class="sheet-health-box sheet-lethal-health">☓</span>                              <span class="sheet-health-box sheet-aggravated-health"></span>                          </div>  It looks like this on the page:        Any ideas if this is doable?     Cheers  Chris
