Patch a multi-select combo box to a nested table within a collection

I'm pulling my hair out for 2 days now and I have no idea if what I am wanting to do is feasible.

I have a collection that grabs data from a SP list called Skills. One of the columns called Workgroup will be used to store values from a multi-select combo box. So I created it as a table.

This is what I did

ClearCollect(colSkillsFoH, AddColumns(ShowColumns(Filter(Skills, Portfolio.Value = "Front of House"), ID, Title, Portfolio), Workgroup, Table({Value: ""})));

I have then added a multi-select combo box into my gallery. On the OnSelect property of the combo box I need to be able to patch or update the selected items from the combo box back to the Workgroup table column that I have created in my collection but to no avail.

Patch(colSkillsFoH, LookUp(colSkillsFoH, Title = ThisItem.Title),
    {Workgroup:{Value: ThisItem.Value}})

It is failing because it expects that the Workgroup column contains a table but is seeing a Record (which makes sense).

I also tried it this way but it's failing on Value. It's also saying that it's expecting a Table value but of a different schema.

Patch(colSkillsFoH, LookUp(colSkillsFoH, Title = ThisItem.Title),
    {Workgroup: Collect(LookUp(colSkillsFoH, Title = ThisItem.Title).Workgroup, {Value: ThisItem.Value})})

How do I get those values to be stored in a table? Is it possible?

My plan is once those values are patched. I will then patch the entire collection to another SP list where the Workgroup column is a multi-select choice column.

Seriously, I can do this with one value but dealing with multi-select values is driving me nuts!

Hi @TerriyakiIR,

If you are triggering the Patch OnChange of the Combo Box, you can do this.
Patch( colSkillsFoH, LookUp( colSkillsFoH, Title = ThisItem.Title ), {Workgroup: Self.SelectedItems} )

Thanks so much! That helped. I was trying this bit out
{Workgroup: ComboBoxName.SelectedItems}
yesterday and for some reason it wouldn't work. There could be a combo of factors as I was trying out too many stuff to the point my app kept crashing lol. I removed my brackets for [ThisItem.Workgroup] in the DefaultSelectedItems property which was causing it to fail (thanks for point that out). And I have to make sure that I put the patch command on the OnChange property as well.

H i @TerriyakiIR,

If you have this in your Patch, assuming the output of your Combo Box is .Value, you are running this from an icon/button inside the gallery and using your Combo Box name
Patch( colSkillsFoH, LookUp( colSkillsFoH, Title = ThisItem.Title ), {Workgroup: ComboBoxName.SelectedItems} )

you can also have the DefaultSelectedItems of your Combo Box
ThisItem.Workgroup

and see the result as soon as it is Patched
