This code works €“ when a user clicks a cell, they are taken to another
worksheet, and a cell range is given blue exterior borders. Then the idea is
to position the worksheet relative to cell A1, then move the cursor
off-screen to B100.

Two problems:

1.) I can't make the A1, B100 code lines work.
2.) If the user moves off the worksheet, or exits, I want to restore the
changed borders to thin/black.

Can someone help fix this?

Thanks, Phil
