Hello, I would like an alert system, when the right blue and red right of my template are both pasted! I want an alert system when two things are glued! Be it the blue line with the red line! Or a trendline with a line or red or blue. I really want two things to always be stuck and there is a warning system!   Who can do this to me? as quickly as possible !! Within 20 minutes for example
