ForAll in Patch Question

[ericonline]

Hello, 

I'm using a new pattern for Form building and could use some help on a ForAll function.

Goal: 

- To Concatenate items in colSelectedResponses Collection which have the same ID and Patch them to the data source.

- Example: The two items below where id = 2 need to be concatenated and Patched to the data source as "Hammer; Ball Peen"

Scenario:

- Variable created from a table of data

Set(
    varItems,
        Table(
            {id: 1, item: "Wrench"},
            {id: 2, item: "Hammer"},
            {id: 2, item: "Ball Peen"},
            {id: 3, item: "Screwdriver"}
        )
)

- Gallery with Checkbox controls. Items Property set to varItems

- OnCheck of Checkbox

Collect(
    colSelectedResponses,
        {
            id: ThisItem.id,
            value: component_checkbox.Text
        }
)

- Button to Patch values has OnSelect Property set to:

Patch(dataSource,
    Defaults(dataSource),
    {
        dataSourceColumn1: LookUp(colSelectedResponses, id = 1, value),
        dataSourceColumn2: 
                ForAll(
                    Filter(colSelectedResponses, id = 2),
                    Concatenate(value, ";")
                ),
        dataSourceColumn3: LookUp(colSelectedResponses, id = 3, value),
    }
)

- The ForAll is not correct syntax. 

Any help is appreciated!
Thank you

Figured it out with some help from @KickingApps!

Concat(Filter(colSelectedResponses, id = 31), value, "; ")

Yay!
