can u please help me this?

what info type of s? utilize whos s find out.

if it's not double, char, or cell won't able assign string edit box. error message tells you.

i don't have symbolic math toolbox can't check code, i'm guessing s symbolic array. if case, see documentation char convert symbolic array string can assign properly.
