Calling Sub Channel Entries How would you go about pulling a selected entry from one channel into another entry using Craft variables?

For example, I have a page with an author channel field that allows a user to select the author from entries in an author channel. Once selected, I am wanting the page to display the author content from the selected Author entry.

I have tried using the following but have gotten no output.

{% if entry.authorTeamMember|length %} 
    {% set myEntry = entry.authorTeamMember.first() %}

    {{entry.authorName}}
    {{entry.authorDescription}}
{% else %}
    &lt;p&gt;No Author&lt;/p&gt;
{% endif %}
You're close!

You select the author correctly with and assign it to the myEntry variable:

{% set myEntry = entry.authorTeamMember.first() %}


Now you just need to output the data from myEntry instead of entry.  i.e.

{% if entry.authorTeamMember|length %} 
    {% set myEntry = entry.authorTeamMember.first() %}

    {{ myEntry.authorName }}
    {{ myEntry.authorDescription }}
{% else %}
    &lt;p&gt;No Author&lt;/p&gt;
{% endif %}
