These may seem a trivial questions, but I've only been using Squiz Matrix for a few weeks now.
Firstly In the Thank You Bodycopy of an online quiz I want to thank the respective user by name, i.e. either the logged in users first name or the name captured in the User Details Form.
Working on the proviso that the logged in user won't be presented with the user details form and therefore can assume that the name won't be entered.
Noting that the name is a mandatory field on the user details form.
I initially tried:
%globals_user_attribute_first_name^empty:user_details_form_11281-q1% - but realised the public user has a name 'Public'
So I switched the statement around:
%user_details_form_11281-q1^empty:globals_user_attribute_first_name% - but now I don't get a name at all!
%user_details_11281:q1_answer^empty:globals_user_attribute_first_name% - but no name
Secondly I'm having difficulty getting the question field name to appear on the user details form and had to hard code it!
User Details Bodycopy 
User Details Form 
Format Bodycopy 
Email address [11281:q2]
Hope there's enough detail in here?
