This is my error message and below is the lines where it is causing the error. I know I have to declare these variables somewhere but in the tutorial it never had me declare these Unicode things. I am unfamiliar with this.

Thank you

void PressureScreenView::UpButtonClicked()
{
 touchgfx_printf("UpButtonClicked\n");
 
 //if (pressureVal < 43)
 {
 counter = counter + 1;
 }
 touchgfx_printf("%d\n", counter);
 Unicode::snprintf(textCounterBuffer, TEXTCOUNTER_SIZE, "%d", counter);
 //Invalidate text area
 textCounter.invalidate();
}
void PressureScreenView::DownButtonClicked()
{
 touchgfx_printf("DownButtonClicked\n");
 
 //if (pressureVal > 21)
 {
 counter = counter - 1;
 }
 touchgfx_printf("%d", counter);
 Unicode::snprintf(textCounterBuffer, TEXTCOUNTER_SIZE, "%d", counter);
 //Invalidate text area
 textCounter.invalidate();
}
