Crystal Reports Shared formula not working like expected in chart.

Message

   I have created a report to compare estimated setup (on a machine, we are a manufacturing company) hours to actual hours.  I have grouped a machine by Job Numbers. Each Job Number has setup labor associated to the Job Number.

In CR for each Job Number, I have created a subreport that shows all the labor time.  I created in the subreport a formula that totals the setup labor time and is shared back to the main form.  On the main form I created a formula "SetupPer" that takes the (EstHrs/sharedsubreport field)*100.  This all works like I expect it to.

Then I create a chart in the group footer using Chart Expert to show each Job Number in the X axis and the SetupPer in the Y axis.  It shows only the last Job Number on the chart.  If I edit the Chart Expert and select EstHrs as the Y axis, then it shows all the Numbers in X and the EstHrs in Y like I expect it to.

Can't you use the information in a formula field if it is derived from a "Shared Formula" from a subreport?
