If you look at the "Attributes & Abilities" tab of your character sheet, you should be able to see just about all the attributes your sheet is generating. Each of the attributes has a current and max value. I don't know if STR is your actual stat for your character or a modifier for skills (which might be something like STR_mod). Generally, if you are making a macro as an ability on the character sheet, then you just need to do @{attribute}. If you are making a macro in your journal, then it will need to be something like @{character name|attribute}. If you are needing the value for the max of the attribute (assuming you assigned a max value), then you would do @{attribute|max} from the character sheet, or @{character name|attribute|max} from the journal. If you are making macros on your character sheet as an ability (Attributes & Abilities tab), then you don't need to tell it what character to look for, because it defaults to that sheet. If you are making them in the journal, then you have to tell them which character sheet to be looking for. The character name has to be exactly as it is on the character sheet, and the attribute names have to be exactly as they are from the Attributes & Abilities tab, or it won't work.
