Removing an item from a collection?

Hi

I have a List Box and OnSelect I want to add or remove to/from a Collection.

The logic is that if the list box item is selected then its added to the collection.

If the list box item is deselected then its removed from the collection.

I try this and it adds to the collection but doesn't remove from the collection.

Any ideas why?

Thanks

P

Notify("Am I blank? Selected is " & listboxClose.Selected.Key);

If(IsBlank(listboxClose.Selected.Key),

RemoveIf(myCloseFirms, galCloseFirms.Selected.FirmName = ChosenFirmName & CloseFirmName = listboxClose.Selected.Key),

Collect(

myCloseFirms,

{

ChosenFirmID:galCloseFirms.Selected.FirmID,

ChosenFirmName:galCloseFirms.Selected.FirmName,

CloseFirmName:listboxClose.Selected.Key

}

)

);

hey @pmwhelan

you can try this approach:

// Assume 'selectedItems' is a collection that tracks the selected state // This snippet goes in the OnSelect property of your ListBox // Check if the currently selected item is in the 'selectedItems' collection If( LookUp(selectedItems, CloseFirmName = listboxClose.Selected.Key), // If it is, remove it Remove(selectedItems, LookUp(selectedItems, CloseFirmName = listboxClose.Selected.Key)), // If it's not, add it Collect(selectedItems, {CloseFirmName: listboxClose.Selected.Key}) ); // Then, sync 'myCloseFirms' with 'selectedItems' Clear(myCloseFirms); ForAll( selectedItems as selectedItem, Collect( myCloseFirms, { ChosenFirmID: galCloseFirms.Selected.FirmID, // You might need to adjust this logic ChosenFirmName: galCloseFirms.Selected.FirmName, CloseFirmName: selectedItem.CloseFirmName } ) );

Let me know if my answer helped solving your issue.
