InfoPath Dev

 Hi,

 we have InfoPath 2013 Enterprise version

 I am trying to open a second list form from another list form, depending of what the user selects on a particular field (there are two list involved here)

 This link shows the required option: "Open another form"

 https://support.office.com/en-za/article/Add-rules-for-performing-other-actions-5322d726-b787-4e5f-8d37-ba6db68b451d

 but I only get four options when adding a rule and the one I need is missing

I appreciate any guidance

Regards 

Not all rule actions are available in all types of forms. I think that SharePoint List forms aren't going to allow you to open another form...
