I gave a name to my main form. When I call another form from this one, I disable it. When quitting the other form I can give an enable statement from the form I'm closing and I get the desired effect.
When I put the name of the form in the watch I can see the whole object.

I tried to use this same effect with another form in the same program, but I can't make it work. It gives the error that the object does not exist.

What am I doing wrong?
