base = game.Workspace.SurvivorCount missionstxt = script.Parent.missions if base.S1.Value == true and base.S2.Value == true then missionstxt.Text = "Mission One Complete!" end
This script's location can be found here. This script is supposed to detect too see if both values are true, and if they are, they change the text of the textlabel (variable missionstxt).
You probably want a changed event so you know when they are changed.
For example:
base = game.Workspace.SurvivorCount missionstxt = script.Parent.missions base.S1.Changed:connect(function() if base.S1.Value == true and base.S2.Value == true then missionstxt.Text = "Mission One Complete!" end end) base.S2.Changed:connect(function() if base.S1.Value == true and base.S2.Value == true then missionstxt.Text = "Mission One Complete!" end end)
