ignore filter if radio buttion value is none

[kashy]

I have radio buttons on a different screen and I'm trying to filter the data as per the selection.

Filter(Purchases, CategoryTxt=thisCat,If(warr="Out of Warranty",DateValue(Expiry_Date)<Today(),If(warr="Under Warranty",DateValue(Expiry_Date)>Today(),false)))

But, the issue I'm facing is, when radio button value is none, I need all items to be shown.

How can I achive this?

Have tried using the switch statement. It could execute different Filters based on the value of the radio buttons. It would look something like this:

Switch(warr, 
  "Out of Warranty", 
  Filter(Purchases, 
    CategoryTxt=thisCat, DateValue(Expiry_Date)<Today()
  ),
  "Under Warranty",
  Filter(Purchases,
    CategoryTxt=thisCat, DateValue(Expiry_Date)>Today()
  ),
  Filter(Purchases,
    CategoryTxt=thisCat)
)

I did this freehand, so there could be some typos.
