Hi, I have a workbook with multiple worksheet, one of the sheets i use 
Please Login or Register  to view this content.
to display a web page that I use to find addresses by entering the postal code into a search box.

When I open the workbook and go to the worksheet that contains the web page I get a script error message Screenshot 2018-04-22 10.40.31.png
If I continue the search still works fine but the pop up is just annoying, is there anything I can do to stop the pop up error?

Many thanks
