Python - one if of a "while" loop works only once (at the beginning)

the "if pulses > 20 and spinning == 0" only works once at the beginning of the script, after "one" spin by pressing the spin-button (input_state == False) the if segment doesnt work anymore (after the variable "isSpinning" is set to 0) in contrast to all the other if segments like: "if input_state2 == False and credits > 0 and spinning == 0" (works).

while mode == "normal":



input_state2 = GPIO.input(18)

    print('Auszahlung')
