I'm still fairly new to lua but have mad e aworking spawn menu with switch to tool gun etc.

I wanted to add self closing so when u release Q it goes away.. i'm getting the error :

My code is:

You need to move the slframe to a global file scope, not inside the proplist() function. Once its outside of that function, close your DFrame with [b]slframe:Close()[/b]

There's so many other things you're doing wrong, but lets start with that first.
