Once you have created a GeneHunter model with the Excel interface, you need to click on the Model button in the GeneHunter dialog box in order to save a copy of the model into your worksheet.  Saving the worksheet does not save the model after it has been run.

Select the Store button to save a copy of the current model.

Select the Restore button to return the model to a previously saved version.

Select the Delete button to remove the version of the model that is currently displayed on the worksheet.

Note:  You must save your model before closing your problem.  If you save only your worksheet, YOU WILL LOSE ALL OF YOUR MODEL CHANGES.
