gsm based led matrix display , GSM interfacing problem

hi

sir i am trying to merge the GSM code with the source code of led matrix display using arduino, and i dont know how to do it.
both codes are given below:

GSM code:

If you have requirements for the resulting program, you forgot to include them, and you forgot to include your attempt to produce that program, and you forgot to say what the problems are.
