If no collection item in gallery is selected send blank

[shaneOZ]

Hi,

I have a gallery that loads its values from a collection to patch into a choice column in sharepoint, i would like if the user does not select a button in that gallery then the patch function is to send Null or Blank, it currently sends the first item in the collection

My on start syntax is 

ClearCollect(
      PitList,
  {PitButt: "LM1", IsClicked:false},
  {PitButt: "LM2", IsClicked:false},
  {PitButt: "LM3", IsClicked:false},
  {PitButt: "SR1", IsClicked:false},
  {PitButt: "SR2", IsClicked:false},
  {PitButt: "SRE", IsClicked:false}
);
Set(CurrentPitButt, Blank());

My buttons on select is 

If(
    CurrentPitButt = ThisItem.PitButt || CurrentPitButt = Blank(),
    Set(CurrentPitButt, ThisItem.PitButt);Patch(PitList, ThisItem, {IsClicked: !ThisItem.IsClicked}),
    Set(CurrentPitButt, ThisItem.PitButt);UpdateIf(PitList, true, {IsClicked:false});Patch(PitList, ThisItem, {IsClicked: !ThisItem.IsClicked})
)

Any help would be appreciated. 

Thankyou 🙂

Sorry for the late reply,

The project was put on hold and i was off playing with powerBi however i now need to solve this one,

PitButt is just the collection name, the column it references in sharepoint is simply called Pit it is a choice column and is patched via the following code,

If(Connection.Connected
	,Patch('Haulage Log',
		Defaults('Haulage Log'),
		{
            Pit: {Value: PitGallery.Selected.PitButt}		
		}
	)
	,Collect(HAULAGECOLLECTION,
		{
		 Asset: Can_Assetid.Selected,
            Pit: {Value: PitGallery.Selected.PitButt}	
		}
	)
)

it patches succesfully. However if the user doesnt select the pit (which happens) it sends the first  value "LM1" in the collection and i would like it too send nothing if unselected.

I should also say ive tried using the 

ClearCollect(
      PitList,
  {PitButt: "", IsClicked:false},
  {PitButt: "LM1", IsClicked:false},
  {PitButt: "LM2", IsClicked:false},
  {PitButt: "LM3", IsClicked:false},
  {PitButt: "SR1", IsClicked:false},
  {PitButt: "SR2", IsClicked:false},
  {PitButt: "SRE", IsClicked:false}
);
Set(CurrentPitButt, Blank());

However i do not want to have a empty button in the app, can i hide the button somehow?
