Greetings to all... Brand new to the forum and currently pulling whats left of my hair out and could use some expert advice!

I have a weekly scheduler, very simple table with Monday through Sunday, and 12 lines that I'll list a certain task to be accomplished. If my first listed task is to, lets say "Install revised FMS software" and I plan to do this Tuesday through Friday, I'd like to find a way to have excel draw the arrow between Tuesday and Friday for me, possibly from highlighting the specific cells I want the arrow, or typing an X in Tuesday and another X in Friday... Is this possible?

I'm open to any suggestions, comments, complaints or good-luck wishes.

Thank in advance
