title: Use a summary field in an expression in SSRS reports
body: <p>I have the details of my report being summed up in a summary expression, all works fine.  The fields are decimal values of hours worked.  Thus, the summary value is also a decimal value.  I'd like to access the summary value and convert it to hours / minutes.  I've labeled the express as "WorkTimeSum", but can't seem to get a handle to it, however.  Fields! obviously won't work since it is a summary expression.  I was thinking ReportItems! should work, but to no avail.  How can I use this expression field (in a summary row) in an expression in the same summary row?</p>
