Custom System: Number value to get dice rolls

A buddy of mine is developing his Own system, and one of the core mechanics is computing a Dive Value (DV) and then useing that value, roll a number of dice. Skill + Attribute = DV So in a nutshell: 1 = D2 2 = D4 3 = D6 ....... 6 = D12 7 = D10+D4 8 = D10+D6 ... 13 = D12+D10+D4 etc... So I'm wanting to create sheets for use in game, but I'm having a heck of a time trying to get this system to work. I'm not nearly as fluent in HTML/JS as i though i was. What would be the easiest way to accomplish this? I'm thinking a JS script switch in the <scripts> section of the sheet, but i cant figure out how to pass the data back to the roll template I'm using. Another though was to use a hidden input selector, but i can get it to work (Similar to the <fieldset class="repeating_skills"> example. Any help here would be GREATLY appreciated. Thanks all!

So like this: <button type='roll' value='/roll @{DiceValue}' name='roll_Skill'> switch( DiceValue ) { case 13 : D12+D10+D4 break; }

More like: on('sheet:opened change:example_skill change:example_attribute', function() { getAttrs(['example_skill', 'example_attribute'], function(values) { var diceValue = parseInt(values.example_skill) + parseInt(values.example_attribute); switch (diceValue) { case 13: diceValue = 'd12+d10+d4'; break; // etc. } setAttrs({dice_value: diceValue}); }); }); <button type="roll" value="/roll @{dice_value}" name="roll_skill"></button>

Awesome! Thanks

Using your above code, I'm getting: No attribute was found for @{Tester|dice_value} I also added an input to get the values: <label>Example</label><br> Example Skill: <input type="number" min="0" step="1" name="attr_example_skill" /><br> Example Attr Bonus: <input type="number" min="0" step="1" name="attr_example_attribute" /><br> <button type="roll" value="/roll @{dice_value} + @{example_attribute}" name="roll_example_skill"> Skill </button> Any ideas?
