title: The value cannot be converted to a number
body: <p>Got a critical error like: The value cannot be converted to a number. what can be the problem? Since i tried to write this values like:</p>
  
  <pre><code>1. &lt;cfset ortalama=trim(val(db_maliyet_temp))+ds_toplam_maliyet&gt;
  
  2. &lt;cfset ortalama=val(db_maliyet_temp)+ds_toplam_maliyet&gt;
  
  3. &lt;cfset ortalama=db_maliyet_temp+ds_toplam_maliyet&gt;
  </code></pre>
  
  <p>the first and second are just doesnt count the db_maliyet_temp,
  and the 3 give out the error: The value cannot be converted to a number.</p>
