ожидаемый неквалифицированный-id перед "while"

Привет У меня есть проблема на коде im пытается потопить 2 кода, но я получаю этот код ошибки

PIGGYBANK_CODE:75:1: error: expected unqualified-id before 'while'
 while (coinInserted) {
 ^~~~~
PIGGYBANK_CODE:82:1: error: expected unqualified-id before 'if'
 if (coinCount >= requiredCoins) {
 ^~
PIGGYBANK_CODE:112:1: error: 'lcd' does not name a type
 lcd.print("Welcome"); {              //Printing a message for the recognized template
 ^~~
PIGGYBANK_CODE:112:23: error: expected unqualified-id before '{' token
 lcd.print("Welcome"); {              //Printing a message for the recognized template
                       ^
exit status 1
expected unqualified-id before 'while'

/*The two following functions depends on your locking system
  mine has a DC motor that should turn in both ways for opening and closing
  that's why I'm using H bridge, you could have a solenoid with a transistor
  then you'll need only opening sequence but controlling the transistor
  as the closing is spring loaded...
