title: Anylogic Error: Can't Convert from Population to Resource Pool
body: <p>I am a new Anylogic user and I am trying to set up a simple simulation like so:</p>
  <ol>
  <li>I have one ResourcePool named <code>People</code>.</li>
  <li><code>People</code> uses a Schedule named <code>People_Schedule</code> that is sourced from a DB table that has a date column and then the number of resources (employees) avalailable that specific interval.</li>
  </ol>
  <p><code>2020-07-09 10:30</code> <code>32</code><br />
  <code>2020-07-09 11:00</code> <code>35</code><br />
  <code>2020-07-09 11:30</code> <code>40</code></p>
  <ol start="3">
  <li>I have a par of Sources named <code>G_Task</code> and <code>M_TASK</code>.</li>
  <li>Both of these Sources use Schedules that are sourced from a DB that has one column with a date column, a work type column, and then a number of work items (tasks) expected for that specific interval.</li>
  </ol>
  <p><code>2020-07-09 10:30</code> <code>M</code> <code>100</code><br />
  <code>2020-07-09 10:30</code> <code>G</code> <code>50</code><br />
  <code>2020-07-09 11:00</code> <code>M</code> <code>125</code></p>
  <ol start="5">
  <li>I have a specific Service for each of my Sources, but my issue is that when selecting the ResourcePool setting in Properties, there is no dropdown for my ResourcePool named <code>People</code>.  I can type in <code>People</code> which then allows both items to be highlighted at the same time on the grid like maybe they are linked, but when I hover on the error I am getting on the Resource Pool setting, I get this message:</li>
  </ol>
  <p><code>Type mismatch: cannot convert from Main._People_Population to ResourcePool</code></p>
  <p>What am I missing?  I have tried searching through the Anylogic help and through Google, but I am finding nothing.</p>
  <p>As a side question, are there any Anylogic users that have gotten past the learning curve and are comfortable with the level of troubleshooting out there on the web (or lack thereof)?  I am used to being able to search SQL/Excel/Python questions and finding tons of resources almost immediately.</p>
  <p>Thanks,<br />
