Get Webform submission count using custom module
Okay. I figured it out. 

There is a function webform_get_submission_count in the webmodule includes file that does. Just added these lines and got it my count. Sweet and simple. 

module_load_include('inc', 'webform', 'includes/webform.submissions');
$mysubmission_count = webform_get_submission_count($node-&gt;nid, $user-&gt;uid);
