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.
