State machine is not switching the states

Hi All,

I have a very simple workflow which has the state machine. It has 2 states Verification and resubmit.

Initially it will go to verification state which has assign task action. On approval the state machine will end and on rejection of task it is changing the state to resubmit. On resubmit state it wait until user submits the data and it has to change the state back to verification.But once user submits the data it is not changing the state to verification. There is no error also.

Please help in resolving this.

Regards,

Hema
