Subject: confusion with gets, if

hi I'm new to ruby and im trying to write some simple codes but i cant
get the 'if's to work. below what i mean. how can i fix the ruby code
for the ifs to work?

no matter what i write it always returns "invalid input"
##################Code#########################
while counter < 1 do
  print ("put 10, 20 or 30 ")
  input = gets()
  if input == '10'
    person1 += 1
    counter += 1
  elsif input == 20
    person2 += 1
    counter += 1
  elsif input == 30
    person3 += 1
    counter += 1
  else
    puts("Invalid input")
  end


end
##############################################



if i were to write it in python i would do it somewhat like this:

##################Code#########################
while counter < 5 :

    vector.append(input('put 10, 20 or 30 '))

    if vector [counter] == '10' :
        p1 += 1
        counter += 1
    elif vector [counter] == '20':
        p2 += 1
        counter +=1
    elif vector [counter] == '30':
        p3 += 1
        counter += 1
    else:
        print ("invalid input")
