You would want to set the textbox's Default property to be a variable. There are a few steps to do first though:

Set the checkbox's OnCheck property to collect the selected item, like so:

//NOTE: I am using colItems as an example, but you can name this collection whatever you want
Collect(colItems, ThisItem)

You would then want to set the OnUncheck property to remove the unchecked item from the collection:

Remove(colItems, ThisItem)

Finally, you want to set the textbox's Default to translate that collection into a text value separating the values by a comma and a space, while also not adding the comma and space on the end if there isn't another record:

With(
{concatResult: Concat(colItems, ThisRecord.Value & ", ")},
Left(concatResult, Len(concatResult)-2)
)

This should get you the desired outcome.

Thank you for your help! I'm having trouble getting it to work. It doesn't like "Value," and I'm not sure why. I also don't know what this refers to. I'm very new to this. Can you help me understand?

Hi @stellarwheels ,'

What is the Text of your Checkboxes ? It will be ThisItem.???? (see below) - The Default of your Text Box just needs to be

Concat( Filter( YourGalleryName.AllItems, YourCheckboxName.Value ), ????, ", " )

Please click Accept as solution if my post helped you solve your issue. This will help others find it more readily. It also closes the item. If the content was useful in other ways, please consider giving it Thumbs Up.
