Why cant my forms be submitted?

I have published my forms. Why but I cant complete an submission ,,, there is no submit button available. Did I miss adding that option. Please help !

I just checked your form and it has the submit button:

The form is available, so it can be submitted. Just to let you know, if by any chance you do not see the submit button in a form, that can be included from the Basic Fields tab when on edit mode of your form. Let us know if you need more help.
