How to delete parameters - Uncleared message error
1- I was watching a tutorial and followed it to set parameters, They appear each time I open Gmesh. I don't know how to delete it.
2- I have errors seen in the screenshot, "Unknown variable Hight, Line 61 could not be added, start and end points should be different". I don't know where are these errors, they don't appear in the script. I don't have the variable H, or lines 61 or 78, These messages keep appearing and I don't know from where.
