It seems that the slider doesn't seem to work. Moving it doesn't register on the Console, like there was no change. Making a change in a connected input type number will move the slider to the right place. <input name="attr_objectiveTrackEarned" type="range" min="-500" max="1100" value="0" style="width:100%; height:100%; vertical-align:middle" /> <input name="attr_objectiveTrackEarned" type="number" style="width:95%; text-align:center" value="0" /> <input name="attr_objectiveEarnedMod" type="number" style="width:95%; text-align:center" value="0" /> <input name="attr_objectiveEarnedTotal" type="number" style="width:95%; text-align:center" value="floor(@{objectiveTrackEarned} + @{objectiveEarnedMod})" disabled />
