Cannot submit to database with hidden variable under conditional

Hi,

You have to use hook_webform_submission_presave() to set default value of form element.

Create custom module and place following code into your custom module file. Check its working fine.

/**
* Implements hook_webform_submission_presave().
*/
function custom_webform_submission_presave($node, &$submission) {
   if($submission->data[1][0] == 'A') {
           $submission->data[3][0] = 0;        # Set Default Value of Variable A
   }
   else if($submission->data[1][0] == 'B') {
           $submission->data[2][0] = 0;        # Set Default Value of Variable B
   }
} 

Let me know if you face any further query/concern regarding this.
