Select method of Range class failed error message

Hi,

I've been trying to customize a design table Excel file so that a user input form can be used to allow data entry that will update the cell values in the design table.  The User Input form is on a separate sheet in the Excel file.  I often get an error stating "Select method of Range class failed" when I attempt to save the SolidWorks part file after modifying the design table.  This always happens after the "Saving linked design table..." message appears.  I have no macros or code in this file.  I do have a few checkboxes that I use to change the suppressed state of features in the design table.  I can't figure out why this keeps crashing - can anyone offer any suggestions?  I have attached the simple Excel file for reference.  I am running SolidWorks 2013 SP3.0, MS Office 2010, and Windows 7 x64.

Thanks!

Dan
