Cancel form after it has been submitted

[Arianeb]

I really need help, I'm trying to add a Cancel link/button to my form to end all workflows except the current one after the form has been submitted as seen in attachment A
and control setting as shown in attachment B
I added js to custom Javascript but my worflow is not starting. Please help.

the code seems to be correct.

does it throw any error? or how does it behave?

isn't worklfow being started already running on a given item?

btw, attachemnts A and B are missing...
