Use checkbox to dictate results for Roll Template

Hello all, I'm trying to work out the correct way to make a change to a roll result based on a checkbox. Specifically, if the checkbox is checked, I need to add another roll macro. Macro call is: &{template:magus} {{name=@{character_name}}} {{trait_name=@{trait1desc}}} {{result=[[{{@{dicepool}}>@{difficulty} + {@{trait1dice}}>@{difficulty}}]]}} and the template itself is: <rolltemplate class="sheet-rolltemplate-magus"> <table> <tr><th>{{name}}</th></tr> <tr><td>{{trait_name}} </td></tr> <tr> <td class="result">{{result}} Successes</td> </tr> </table> </rolltemplate> e.g. : If the box is unchecked, the macro should be: {{result=[[{{@{dicepool}}>@{difficulty} + {@{trait1dice}}>@{difficulty}}]]}} If the box is checked, the macro should be: {{result=[[{{@{dicepool}}>@{difficulty} + {@{trait1dice}}>@{difficulty} + {@{magicitem1dice}}>@{difficulty}}]]}} I'm open to alternative ways of doing this - I thought I could instead use the checkbox to control whether a section is shown or not, and always roll and display the extra dice separately, but I couldn't figure out the property logic. Any help is much appreciated!

Hi Duno, One option that should work(untested); Change the default macro to add the checkbox attribute. [[{{@{dicepool}}>@{difficulty} + {@{trait1dice}}>@{difficulty}} + @{checkbox_foo}]] Change the value of the checkbox ( usually  it's value="1" ) to the macro you want to include if checked. attr_checkbox_foo value="{@{magicitem1dice}}>@{difficulty}" So unchecked, checkbox_foo would be value="0" or "{@{magicitem1dice}}>@{difficulty}" if checked.

Hey Vince, thanks for the idea, but no go. I added a checkbox like so: <input type="checkbox" name="attr_magicitem1check" value="{{@magicitem1dice}}>@{difficulty}}"/> And added to the result: {{result=[[{@{dicepool}}>@{difficulty} + {@{trait1dice}}>@{difficulty} + @{magicitem1check}]]}} but that only ever returns 0 when unchecked and 1 when checked, I can't get it to return the dice roll results (and it doesn't seem to calculate it either - even if I say '2d4>1' it gives me a 1). Even worse, when it does return 1 (i.e. is checked) it doesn't add that 1 to count of successes. Wait a minute... That value's wrong. It should be: value="{@{magicitem1dice}}>@{difficulty}" and... hey, it works! Righteous. You're the best, Vince.
