How would I shirt a team's players VIA StringValue in workspace?

I've tried multiple ways of doing this, I used a 'for' loop, used a .Changed() function on the value In workspace, nothing worked. So I figured I'd come here for help.

When I say VIA stringvalue, I mean, If the value, team1, changes to "Alabama", then It gets the players of team1 [ AKA Deep blue team color] , and It changes their shirt to an alabama Jersey. If anyone could help me with this, I'd highly appreciate It.

Did you set the .Changed properly?

So like it would be something like this. Let's say "Teemo" is the StringValue in the workspace.

workspace.Teemo.Changed:connect(teemo)

It will now connect to a function named "teemo".

function teemo()
-- do what you need to do here.
end

Now all you need to do is add an if statement for the value of the string(like "if teemo.Value == "mushrooms" then do whatever end)

I'm assuming you already know how to change their shirt because you are saying that you are having trouble with connecting it to a function or a loop.
