Yes, as @timl you should use that documentation as a guide.
I notice you want to use it as SharePoint List item. So then in the Form Item property you should LookUp the Record by the Param("Id"). Note that both the letters L and the U are capitalized in LookUp
Item property of your Form:
//pseudocode
LookUp(MySharePointList,ID=Param("Id"))
To be cleaner, it may be better to make sure it is not blank as well, and then put something else for the Item property in the case that the ID param was not provided, so you might prefer this one instead for Item property of Form
//pseudocode
With
(
{myId:Param("Id")}
,If
(
!IsBlank(myId)
,LookUp(MySharePointList,ID=myId)
,Blank()
)
)
In the above, you could replace Blank() at the end there, with whatever you might prefer it to use for the Form Item in the case the Param Id was not provided.
However, just using the simple one line
LookUp(MySharePointList,ID=Param("Id"))
for the Form's Item property, may be the simplest and the best, if it fits your scenario.
See if it helps @JürgenD
