Module I'm making errors at returning? Why?

𝐓𝐡𝐢𝐬 𝐡𝐚𝐬 𝐛𝐞𝐞𝐧 𝐬𝐨𝐥𝐯𝐞𝐝!

Here is the error for context:

In case your wondering:

I’ve been making a module called “PluginService” for a couple days now, but for some reason it’s erroring at returning. I’ve researched it and can’t seem to find a solution.

Please provide me with any information you may have on this matter.
Appreciate your help!!!

I sense invalid syntax if Plugin ~= nil then Plugin_ = Plugin Settings = Plugin_:GetSetting(“Settings”) end
in PluginService:SetDefaults

NxYz · December 3, 2025, 7:16pm

Does your script actually throw an error?

PretzlNoob · December 3, 2025, 7:20pm

Yes it does:

Can u do a slightly bigger image

NxYz · December 3, 2025, 7:32pm

There’s just syntax errors in your code fix em
Missing end:

if SetToNil then Plugin_:SetSetting("Settings", nil)

Two statements on one line:

Plugin_ = Plugin Settings = Plugin_:GetSetting("Settings")

Just some quick notes:

You should post the actual error, so it’s easier to debug.
You should properly format your code so it’s easier to read

The problem with your module is a missing “end” statement at the end of the file. I’d recommend using proper formatting to catch these errors in the future.

Thank you for the help! sorry for any inconveniences!

fletc3her · December 3, 2025, 7:46pm

BTW, the Script Analysis window is a great way to keep track of syntax errors and warnings while you’re coding. It’s at Windows > Script > Analysis in studio for me. Check the “Display only current script” option and it will highlight errors and warnings in the script you’re editing.
