Multi Steps Form

Hello to all,
I am trying to make a multi-steps form. I am following the tutorial exactly as is. My problem is probably with the variable. When I finish my form all the steps keeps open. All the btn works. In the variable I am set the value to 1 and them in the dynamic event of each bottom I placed the variable value + 1, them in the dynamic attributes in each row I placed the variable value ==1, ==2, … Someone had the same problem that may give some light.
Thanks
Alex
