The problem refers to the timing of lcd functions which aren't shown in your post.
 

You have to set pins connected to LCD as output pins and you have to initialize LCD. If you try to write to LCD without initializing LCD then you get this error in Proteus.

Dear Milan.rajik
I did whatever you have said, but the problem not solved,
the hole of my code is below, i think must be something wrong in loops of my code.
