Show name in Custom Html

I want to show the first name in a Custom Html but it´s not working. I activated "Prepare Content" and this is the code that I use in my CUstom html module:

<p>Hola, [cb:userdata field="firstname" /]</p>
 

You'll need CB Content Module or CB Content Bot to accomplish that. Substitutions aren't supported in content otherwise. CB Content Bot would enable substitutions anywhere Joomla content plugins are supported. CB Content Module is like a more advanced Custom HTML module and also supports substitutions out of the box.

You can also add a substitution supported greeting to your CB Login Module, which is included with CB for free, by editing your login module then under "Logout Options" configure the "Logout Pre-text" parameter to your liking. That should then show at the top of your login module once they login.
