title: Excel Chart title will not accept a date concatonated to a string
body: <p>I'm trying to include a date in my excel chart title by putting a formula inside the title formula box:</p>
  <p>=&quot;Some text &quot;&amp;TEXT(NOW(),&quot;mmm dd&quot;)</p>
  <p>I've tried putting the date into a cell, and referencing the cell, but that doesn't work:</p>
  <p>=&quot;Some text &quot;&amp;TEXT(Statistik!$H$26,&quot;mmm dd&quot;)</p>
  <p>Strangely, I can put a date into the chart title:</p>
  <p>=Statistik!$H$26</p>
  <p>But as soon as I add text (&quot;eg &quot;&amp;), it gives me an error message that there is something wrong in the formula. If I paste the same formula into a cell, it works fine. =Concatonate doesn't work either.</p>
