if in lists

Hi,
I looked ( www.joomlapolis.com/documentation/279-community-builder/tutorials/18624-cb-html-field-and-cb-substitutions-video ) to see that I have to make seperate fields for "firstname lastname" in one line, in lists. Then I wanted to include if, to suppress some fields - public/registered. But every ( www.joomlapolis.com/documentation/18353-using-substitutions-throughout-cb ) if in this seperate fields doesn't work. What's my mistake?
CB 2.1.0, J 3.6.5

No idea what you're asking, sorry. Substitutions for fields work in userlists whether description, label, or layout. This includes the IF substitutions. If for example you need a description unique to a location you can use the reason condition (note this only works for fields) as follows.

[cb:if reason="list"]This will only display when on a userlist.[/cb:if]

I used pic1 for the field, but unlogged and logged the name appears...

I've tried following "if" statements for preparing different looks for my list. None is working! I wanted to display an eMail in the list only if the user is logged in, but the eMail is displayed always (logged in or not)! The normal "[firstname] [lastname]" as an "own HTML" for example is working in list.

[cb:if username="demo"]This is Demo being displayed.[/cb:if]
[cb:if viewaccesslevel !includes "1"]I am NOT Public[/cb:if]
[cb:if usergroup !includes "2"]I do NOT have Registered Usergroup[/cb:if]

or vice versa!

works!

[cb:if user="#displayedOrMe" user_id>"0"]

Field conditions are always based off the profile owners user object. If you need them based off the viewing user you use user="#me". If you want it to be based off the displayed user when possible then use user="#displayed". If you want it based off displayed when possible otherwise self then use user="#displayedOrMe". If you want to display something based off the profile owner being logged in you need to condition against the onlinestatus field (true/false/1/0 values should all work). See the below substitution tutorial below for further substitution usage information.
