Hi Poonam
You need to make the following changes:
This needs to be a triggered smart campaign. In the smart list choose "Fills Out Form" as the trigger, and choose the form you are filling out.
In the flow, if you are trying to send yourself an email when somebody fills out the form, you need a different flow action. This flow action would send an email to the person who filled out the form. If you want an email sent to you whenever somebody else fills out the form, you need to choose the "Send Alert" flow step, and put your email in the "Other emails" box.
