email submit cakeslice in content blocker, clicks but no submits, HUH?

ok i dont understand i have an iframe of another site and then i add the content blocker and put the cakeslice of an email submit form in the content blocker, i just got 32 clicks but it says no submits? huh...
how is this possible i thought if it was a 1 page email or zip submit and you put it in a cakeslice isnt it supposed to be an automatic submit once they enter the email,lol. can anyone tell me why i am getting only a click in my stats...
