It seems like you need to create a new object of type DPS. Use the Create object action and set it before the Show Page (repeat this for all the objects you need).
And then double click on the show page action to update the parameter with the object you just created.
In any case, also check if you are using the correct parameter inside your page (maybe you are using a wrong Entity here):
It seems like you have a lot of page parameters there, check if every one of those parameters is needed and if not, delete the unnecessary ones.
I hope that solves your issue, best regards!
