title: crystal reports : global subreport variable sum not transferring to parent main report
body: <p>I am running crystal reports 11 and in the main report is a subreport which calculates the balance.  In the subreport balance, I have the formula named balancetotal which manually sums the running total of the tarinvoice.balance field.  </p>
  
  <pre><code>WhileReadingRecords;
  global numbervar balancetotal;
  balancetotal := balancetotal + {tarInvoice.Balance}
  </code></pre>
  
  <p>In the main parent report, i have a formula named balancetotal with this formula:</p>
  
  <pre><code>    global numbervar balancetotal;
      balancetotal;
  </code></pre>
  
  <p>is this incorrect?</p>
  
  <p>thanks in advance</p>
