Tool Weld script not working (anymore), any help?

Hi there. I seem to be having some trouble with this script for welding parts in a tool...

for _,v in pairs(script.Parent:GetChildren()) do
local weld = Instance.new("Weld", game.Workspace)
weld.Part0 = script.Parent.Handle
weld.Part1 = script.Parent.Grip
weld.C0 = CFrame.new(0,0,-0.5)
end

The funny thing is, this used to work. I added some other parts to the script to weld, and then this error started popping up in output:

07:45:12.385 - Workspace.Tool.Weld:4: bad argument #3 to 'Part1' (Object expected, got CFrame) 07:45:12.386 - Script 'Workspace.Tool.Weld', Line 4

Even after I removed all of the other welds from the script, this error still occurs. I'm not very good at scripting, so the answer is probably staring me right in the face, but I would appreciate any help.
