macro for adding and keeping the result

I run a resource homebrew system that where characters roll for Ore, Food and Wood. I have been manually putting their results into a text box within a drawn box.  I want to make a macro where their rolls will added and updated without me having to add their result manually.  I have done the following: make a character sheet called "camp resources".  in the character sheet , made new attributes in the "attributes and abilities tab". called wood, ore and food.   Now, what I want to do is have the macro that the players roll update the  "camp resources" character sheets wood, ore and food what is the command that ties to the sheet to add and store values from a dice roll from the resources?

Unfortunately, there's no way to edit Attributes from anywhere but the Attributes & Abilities tab of a Character without the assistance of a customized Sheet Worker Script or an API Script. Access to both Custom Character Sheets and the API are only available in games created by Pro subscribers.

dang, thank you very much.

You could potentially do something that would be 'easy' to update by having a token associated with the journal for the camp. Assign the three bars to Wood, Ore and Food and then set it as the default token. Whenever you needed to update it the players could make their rolls and then just type +[roll result] into the associated bar's bubble to increase it by that amount. It isn't much quicker than going into the sheet really but means you don't have to have the sheet open to do it?

thanks, looking for something automated though
