How can I select different part names within a function?

function generateMedKit(name,XYZ) 
	local MedKits = game.ServerStorage.MedKits.name  
		MedKits.Position = XYZ                       
		MedKits.Parent = game.Workspace             
	end                                             
generateMedKit("Med1","Vector3.new(463.39, 28.452, 220.52)")
generateMedKit("Med2","Vector3.new(463.39, 28.452, 208.84)")
generateMedKit("Med3","Vector3.new(463.39, 28.452, 196.33)")

I understand what is not working here, but I am not sure how to fix it. The variable is being set to "game.ServerStorage.MedKits.name", but I need the script to make "name" whatever I write within the argument like "Med1" that way for each function I call I can select a different part within the ServerStorage.

function generateMedKit(name,XYZ) 
	local partName = name
	local MedKits = game.ServerStorage.MedKits.partName
		MedKits.Position = XYZ                       
		MedKits.Parent = game.Workspace             
	end                                             
generateMedKit("Med1","Vector3.new(463.39, 28.452, 220.52)")
generateMedKit("Med2","Vector3.new(463.39, 28.452, 208.84)")
generateMedKit("Med3","Vector3.new(463.39, 28.452, 196.33)")

I also tried doing it this way trying make "partName" a variable of the "name" I wanted, but it didn't work.

Sorry if it is hard to understand what I'm asking, I just started scripting and can't explain this stuff well yet. I'm not even sure if any of this script could even work.
