How can I correct this function compile error?

T-57:
Well it compiles now, but how can I change the values of the two functions into numbers which I can print to my LCD?
This will be counting down as the program goes on.

  int myprescriptionfunctionA (int days, int iterations)
  {
    int remainingA;
    remainingA = days - iterations;
    return remainingA;
  }

There is no need to separate the declaration and initialization of the variable. So, this should be:

  int myprescriptionfunctionA (int days, int iterations)
  {
    int remainingA = days - iterations;
    return remainingA;
  }

Since the intermediate variable is not needed, it could be:

  int myprescriptionfunctionA (int days, int iterations)
  {
    return days - iterations;
  }

Which really makes be wonder why you need a function call at all.

By the way, I don't understand your question. Which values do you need to change to numbers (which makes no sense as values ARE numbers)?
