You wrote

a = +1

Which sets a equal to one. If you want to increase the value of a, use

a += 1

which is equivalent to

a = a + 1

thank you very much for your answer but it says
"invalid operants 'nil' and int in operator '+'"

Oh, sorry I missed that first part. You never give a a starting value, so how can 1 be added to it? Assign a an initial value.

i undertsand thank you very much
