So I have an inventory system and I wanna make it so you can sell towers, right now, it removes it from the data but it doesn’t seem to update on the client though when you wanna equip or unequip something it works fine. I have to close and reopen the inventory for it to work? Heres the code on the client:

--for equipping something
local function interactItem(itemName)
	local data = interactItemFunc:InvokeServer(itemName)
	if data then
		playerData = data
		updateItems()
	end
end
--for selling something
function sellUnit(itemName)
	print(itemName)
	if itemName and sellingUnits == true then
		local canSell = sellFunc:InvokeServer(itemName)
		updateItems()
		if canSell then
			updateItems()
		end
	end
end

And then of course, here it is on the server:

--equipping something
replicatedStorage.InteractItem.OnServerInvoke = function(player, itemName)
	
	replicatedStorage.GuiInteract:FireClient(player)

	local shopItem = getTowerByKey(itemName)
	local playerData = data[player.UserId]
	if shopItem and playerData then--if it exists and player has some data
		local status = getItemStatus(player,itemName)
		

		
	if status == "Owned" then
			--equip the tower
			if not table.find(playerData.SelectedTowers,shopItem.Name) then
				table.insert(playerData.SelectedTowers, shopItem.Name)
			end
		
		if #playerData.SelectedTowers > playerData.MaxTowers then
			table.remove(playerData.SelectedTowers, 1)
		end
	elseif status == "Equipped" then
		--unselect(if more that 1 selected)
			local towerToRemove = table.find(playerData.SelectedTowers, itemName)
			table.remove(playerData.SelectedTowers, towerToRemove)
		end
		print(data[player.UserId].SelectedTowers)
		return playerData
	else
		warn("Tower/player data does not exist")
	end
	return false--if something went wrong
end

--selling something
sellUnitFunc.OnServerInvoke = function(playerWhoSell,itemName)
	print(playerWhoSell,itemName)
	local shopItem = getTowerByKey(itemName)
	local playerData = data[playerWhoSell.UserId]
	if shopItem and playerData then--if it exists and player has some data
		local status = getItemStatus(playerWhoSell,itemName)

		if status == "Owned" then
			--equip the tower
			local towerToRemove = table.find(playerData.OwnedTowers, itemName)
			table.remove(playerData.OwnedTowers, towerToRemove)

		elseif status == "Equipped" then
			--unselect(if more that 1 selected)
			local towerToRemove = table.find(playerData.SelectedTowers, itemName)
			table.remove(playerData.SelectedTowers, towerToRemove)
		end
		
		print(data[playerWhoSell.UserId].SelectedTowers)
		print(data[playerWhoSell.UserId].OwnedTowers)
		replicatedStorage.GuiInteract:FireClient(playerWhoSell)
		updateEvent:FireClient(playerWhoSell, data[playerWhoSell.UserId].Gems)
		return playerData
	else
		warn("Tower/player data does not exist")
	end
	return false--if something went wrong
end

(the GuiInteract and updateEvent are different don’t worry about those) Any help is appreciated, thanks!
