Some things in workspace dont have a value and when im looping through it errors is there any way to fix this?


for i,v in pairs(game.Workspace:GetChildren()) do 
    local Value = v.Value -- Some things in workspace dont have a value and it gets stuck there and errors

    print(Value.Value)


end

You can use :IsA to whitelist the classes you want, including values.

You can add this to your script to only include Values you want, for example:

for i,v in pairs(game.Workspace:GetChildren()) do
    if v:IsA("ObjectValue") or v:IsA("BoolValue") then
        local Value = v.Value 
        print(Value)
    end
end

Prints only the values of ObjectValue and BoolValue. Also, if you don't want these values to print nil if they're nil, you can add an extra if v.Value ~= nil under the first if.
