@TimmyBoy ,
I have spent about an hour on this on a model, so will give you what I have - it seems to work, but I will have to leave it to you to play with, understand and finish (you may have different references depending on your Gallery Items)
Firstly, you need to initiate a Collection - Screen OnVisible or whenever you want to start the selection again
ClearCollect(
colItems,
Table({Value: Blank()})
);
Clear(colItems)
Now on the OnSelect of your checkbox
Clear(colSelect);
If(
CountRows(
Filter(
Gallery3_2.AllItems,
CheckBoxName.Value
)
) = 0,
ClearCollect(
colSelect,
MyData
),
ForAll(
Filter(
Gallery3_2.AllItems,
CheckBoxName.Value
) As aSel,
Collect(
colSelect,
Filter(
MyData,
!(aSel.Value in Nota.Value) && !(aSel.Value in colItems.Value)
)
);
Collect(
colItems,
{Value: aSel.Value}
)
)
)
and your Label
"(Results " & CountRows(colSelect) & ")"
