## Troubleshooting Problems

Problem | Solution
Failed: Not enough information was selected | This means either you do not have enough transactions needed to display the particular chart or the required number of transactions needed is set to too high of a value. Try adding additional transactions into the database and if that doesn't work try adjusting your the Subgroup Parameters settings in the Calculation Specifications dialog box. See "Modifying SPC Calculations".
The application hangs or crashes to the desktop | If Datapage+ hangs or crashes, it will generate a crash report which you can submit for review. This report consists of a screen capture at the time of the crash, a log file, and the software's registry information. Submitting this information will assist in efforts to eliminate these problems.
Target Plots |
Invalid format for reference plane | The entry in the Reference Plane box (accessed through the Chart Options | Chart Display | Target Plot menu option) is incorrect. Be sure you have typed valid letters for the reference plane, such as XY. See "Chart Display - Target Plot".
No valid data | The selected features do not have variables in the specified plane, or the variables lack data.
Tolerances not set for selected plane and tolerancing type | Tolerances are not defined in the variable records and default tolerances have not been set. Type the default tolerances or type the upper and lower tolerances in the variable records through the Data Editor tab.
Tolerance ratio must be equal for all features | For Group Target Plots, each variable may have different tolerances, but the ratio of the X to Y tolerances must be identical for all features if you are using Elliptical or Rectangular tolerancing. If the ratio is unequal, the system cannot create the Target Plot. To create the plot, change the variables’ tolerances so that they are equal or their ratios are equal, or use True Position tolerancing.
