I am trying to pass multiple parameter values to be dynamically populated using short code
[gravityform id=8 field_values='firstname=xxxxx&lastname=yyyyy'] . Only the first parameter 'firstname' value is dynamically populated on the form and 'lastname' value is not dynamically populated.
Form is created on http://dev30.visualmediahosting.com/gravityform/.
Can anyone please suggest how to pass multiple parameter values to be dynamically populated on the form using shortcode.
