Patch based on a blank value in a combobox

[MJ84]

I have a combobox where I want it to patch the selection into a SP list if there is a selection made. If a selection is removed (clicking the X on the selected result I want it to patch back to the SP "Available"...

I  have the following line of code on the onchange property of the combobox. The problem is it only patches "Available" never the selection... I think from watching it, it runs through the code Patches the selection from the combobox then it carries on and then just patches back to "available"

Patch('SPList',ThisItem,{Spare1:If(IsBlank(ComboBox2_1.Selected.Result),"Available",ComboBox2_1.Selected.Result)})

Thanks in advance

Don't use IsBlank here use IsEmpty. Like this Example:

If(!IsEmpty(ComboBox1.SelectedItems),Collect(MyColl02,"Some" & Text(RandBetween(10,100))),Collect(MyColl02,"Zome" & Text(RandBetween(1,100))))

Here notice it works see this example where it works and knows when there's nothing or something in Combobox and reacts differently with above formula:
