Thank you for quick response!
but I think you miss understood my question.
What you mean by the global variable has 2 characters?
the name is “Ch01_s02,” so I think this has 7 characters. (see picture04)
and the important thing is that the logic worked fine in Mac (the computer),
but when it goes into the mobile, it doesn’t work.
could you explain more in detail?
Thank you.
