Calling Attribute within another attribute call

I want to do this : @{@{character|attribute}|attribute} But it leads me to this error :  No character was found for '@{character' And it actually write in the chat the correct value for @{character|attribute}. I don't understand how I should do it/what I am doing wrong. If it can help, it will be used in a global macro. So I am asking for your help, please. 

That isn't possible as written, as the parser works left to right rather than inside out - you can get the Attribute reference without error by escaping the outer call: @{@{character|attribute}|attribute} but it won't resolve to a value. You have a few options: 1 - The prefix trick 2 - Use an Ability (abilities are parsed first), so @{character|%{character|ability}} will work if that ability contains a valid Attribute name. This is not overly useful unless you have API to dynamically set the ability content, though there are a few use cases of mass-modifying macros that the DM uses. 3 - Discover a new Stupid Trick that allows the nesting of Attributes I vote you go with the 3rd option
