Form not closing

I have workflow task which opens a form. After the valuse in the form are saved it should trigger next task of sending mail notification with the values.

The problem I am facing is it opens the form, I enter the text save it --

but it's not sending any notification. Now I checked the task and it shows -

Start --> Open Form --> Testing Form -->End Open Form-->notification-->end

Where it shows red on testing form and black on subsequent tasks. Below is the activity on workflow which I think is not going through......

<Activity id='1' name='Open Form F'>

<ManualAction id='0' name='Testing Form F'>

<Owner>

<ref>WF_CASE_OWNER</ref>

</Owner>

<FormRef>

<ObjectRef type='UserForm' id='#ID#2CEC5ABD68FF539B:-4D778E4:10CEEAEE1D9:-7EEC' name='Form-F'/>

</FormRef>

</ManualAction>

<Transition to='notification'/>

<WorkflowEditor x='152' y='117'/>

</Activity>

Any idea ? what am I missing..?
