Sending values from a function to a switch statement outside of the function

Hello everyone,
I'm having a problem with my code where i try to do something like this:

switch (numh)
  {
    case 0:
      //set shift register to 01010101
      break;
    case 1:
      //set shift register to 10101010
      break;
    case 2:
       //set shift register to 11001100
      break;
}

//Something completely different

void DisplaySetHour(int numh, int i, int p)//time display function
{
  if (p == 2) //exit to main menu
 {
    menu = 0;
    menu2 == 0;
  }

  DateTime now = RTC.now(); //GETTING THE CURRENT HOUR VALUE

  if (i == 1)
  {


    if (hourupg == 23)
    {
      hourupg = 0;
      dayupg++;
    }
    else
    {
      hourupg = hourupg + 1;
    }
  }
  if (i == 2)
  {
    if (hourupg == 0)
    {
      hourupg = 23;
      dayupg--;
    }
    else
    {
      hourupg = hourupg - 1;
    }
  }

  Serial.print("Set Hours:");
  Serial.println(hourupg, DEC);
  numh = hourupg;//WRITING THE HOUR VALUE TO THE DISPLAY - DOESN'T WORK
  shifter.write();//UPDATING THE DISPLAY - DOESN'T WORK

}

The problem is that i would expect the code to send the numh value to the switch function where it gets "encoded"and displayed on the display. However, when I upload the code the number doesn't get displayed.
The end goal of this is to get a live readout on a nixie display as you adjust the values.
My full code is attached if you'd want to take a look and give me some advice.
Thank you in advance.

Welcome,

You have to call the function in which there is the switch

void setShiftRegister( uint8_t num )
{
    switch (num)
    {
        ...
    }
}

...

void DisplaySetHour(int numh, int i, int p)//time display function
{
   ...
   setShiftRegister( numh );
   ...
}

I just tried it.
Works great now.
Thank you for this advice.
Here, have some karma.
