What I am wanting to do is use cash and ko's to buy weapons and upgrades.

I have it now were all you need is cash

ok the last script didn't work out very well this is the script that I am using I am not sure if I need to save them some were like I did the cash or what.

PurchaseHandler:

objects = {}
teamcolor = BrickColor.new(script.Parent.Name)

wait(1)

script.Parent.Essentials.Spawn.TeamColor = teamcolor
script.Parent.Essentials.Spawn.BrickColor = teamcolor

script.Parent.Essentials.Collector.Touched:connect(function(hit)
    if hit:FindFirstChild("Cash") then
        script.Parent.Cash.Value = script.Parent.Cash.Value + hit.Cash.Value
