you want to OPEN sample form 1 from sample form 2 ? is that what you mean ?
if so, then you will need to treat this differently. in your ‘connection’ return as well the form instance ID to a hidden field on your form (see here to ensure you know what this is : /Documentation/manual/html/dont_confuse_instance_id_with_.html and then use that in the ShowForm behaviour action to launch the actual form
PS in future , please consiuder using the support ticket for such things where you can also include screen shots that will help explain what you are trying to do a lot easier
