If Variable Exists, Pull it, otherwise Ignore

Hi all, I'm trying to save myself a lot of work regarding a new homebrew rule.  Is it possible in a macro to print an attribute value if it exists, otherwise ignore it? I'm trying to avoid getting a bunch of these messages:   No attribute was found for @{selected|attribute_name} Googling / searching the forums hasn't turned up anything. Thanks in advance. -Adam

It's not possible to do any conditionals (like "If attribute exists, do this") with a standard roll or macro. It's possible to suppress error messages, but the macros still try to use the non-existent attribute, so that's often not useful. It is possible to do this with an API script, and if you're creating or editing a character sheet, it's also possible to avoid this (say, by making sure every attribute has a default value).

Thanks for the quick response.  Adding the new attributes to each sheet (even if they don't need to contain a value) was my plan B.  Sounds like that will be the best route forward. -Adam
