Subscript out of range error in Excel VBA when I add a new worksheet at the end of the list of worksheets only when the VB window is closed - excel

Question

I have built an Excel Workbook that is intended for evaluation of an organization as a whole and then evaluation of each of several sites for that organization. There is an initial assessment and then an on-site assessment for the organization, and for each facility. Depending on the organization, the number of facilities will vary. There is a first "Configuration" tab where the user of the workbook enters (or copies and pastes) the list of facilities and determines which facilities are to be included in the evaluation.
The second and third worksheets are the assessment for the organization as a whole, and the fourth and fifth worksheets are template assessment forms for the facilities.
Once the list of facilities is entered, the user clicks on a button labeled "Create Facility Tabs" that steps through the facility list and creates the needed worksheets for each facility.
If the list is fresh (starting from its initial form), then the template worksheets are renamed for the first facility and new worksheets are created for the remainder.
If there are already worksheets identified, the software checks each facility to see if its page already exists, and only creates additional worksheets for newly added facilities.
When additional worksheets are needed, the code first counts the number of additional worksheets that are needed (two for each facility), creates those worksheets, and then steps through them copying the template contents onto the forms and the change code for the worksheets into the worksheet's module.
The software works perfectly over and over again when I have the VBA window open. It does everything it is supposed to do. However, when I close the VBA window, the code creates all the worksheets, copies everything into the first worksheet, and then raises a Subscript Out of Range error. Any ideas what I am doing wrong?
Here is the code:
