title: "Run Keyword If" and setting a variable
body: <p>The following code doesn't work.
  I want to set a variable if a condition is true.</p>
  
  <pre><code>    Run Keyword If    ${MAC} == 110299160221421    ${device_serial}=    set variable    ${device_serial_1}
  </code></pre>
  
  <p>I get the error:</p>
  
  <pre><code>No keyword with name '=' found
  </code></pre>
  
  <p>This is working but doesn't change a variable.</p>
  
  <pre><code>    Run Keyword If    ${MAC} == 110299160221421    Log to console    111
  </code></pre>
