Here is the script to apply the shirt to my character, and here is the error:
'7:28:19.517 - Image "https://web.roblox.com/catalog/584186378" failed to load in "Workspace.Aquarius_Raverus.Humanoid.Clothes": Request failed'
Here is my script:
script.Parent.CustomizationFrame.Page1.Shirt.MouseButton1Click:Connect(function()
for i,v in pairs(script.Parent.CustomizationFrame.Shirts:GetChildren()) do
v.Visible = true
v.MouseButton1Click:Connect(function()
if player2 ~= nil then
player2:FindFirstChild('Shirt').ShirtTemplate = "https://web.roblox.com/catalog/"..v.Value.Value
end
end)
end
end)
If this is not enough information, feel free to respond to what you need to help me figure this out.

What is the Value you are using in line 6 ? Try using this 584186375, this is the source of the image, not the actual shirt itself
The value I'm using at line 6 is actually the shirt code, not the image label image value.
If all else fails, wear the shirt on your player model, insert your players character model into studio, then just copy that shirt on your character.
Oh yea, and don't use that web.roblox.com string, its not the right syntax, heres the correct one: http://www.roblox.com/asset/?id=
Neither works, but thanks for trying. Still looking for the answer.
