@kinghnvn ,

You cannot reset the concat() function result unless you empty the collection selectedDesks.

If you don't want that you can use a context variable emptyMyLblDesk in OnSelect property of the Back Button:

UpdateContext({emptyMyLblDesk:true})

set the Text property of the LblDesk control to:

if(emptyMyLblDesk,Blank(),Concat(selectedDesks,Title&", "))

and OnVisible property of the screen change the emptyMyLblDesk value to false:

UpdateContext({emptyMyLblDesk:false})

Hope it helps !

There is a bracket missing on If clause formula. I'll correct my previous post.
