title: How to write multiple conditions of if-statement in Robot Framework
body: <p>I have trouble writing <code>if</code> conditions in Robot Framework.</p>
  
  <p>I want to execute</p>
  
  <pre class="lang-none prettyprint-override"><code>Run Keyword If '${color}' == 'Red' OR '${color}' == 'Blue'  OR '${color}' == 'Pink'    Check the quantity
  </code></pre>
  
  <p>I can use this "<code>Run keyword If</code>" keyword with one condition, but for more than one conditions, I got this error:</p>
  
  <blockquote>
    <p>FAIL: Keyword name cannot be empty.</p>
  </blockquote>
  
  <p>And also I would like to use these keywords:</p>
  
  <pre class="lang-none prettyprint-override"><code>Run Keyword If '${color} == 'Blue' AND '${Size} == 'Small' AND '${Design}' != '${Simple}'      Check the quantity
  </code></pre>
  
  <p>And</p>
  
  <pre class="lang-none prettyprint-override"><code>Run Keyword Unless '${color}' == 'Black' OR '${Size}' == 'Small' OR '${Design}' == 'Simple'
  </code></pre>
  
  <p>But I just end up getting errors.</p>
