Mouse.Target is only showing one part?

I'm trying to make a survival game, right now I am working on the gui where it shows the text of what the item is and gives a message about the item,

But It only works on one item, and not the others. please help?

local checkpart = function()
    for items,v in pairs(itemmodule) do
        if mouse.Target == itemmodule[items].directory then 
            changetext(ptb,itemmodule[items].name.. " [E]")
            changetext(tmessage,itemmodule[items].message)
            ptb.Visible = true;
            tmessage.Visible = true;
        elseif mouse.Target == nil or mouse.Target == game.Workspace.Baseplate then
            ptb.Visible = false;
            tmessage.Visible = false;

        end
    end
end

this is the module for the items

folderitem = game.Workspace:WaitForChild("folderitem");
local data = {
        flashlight = {
        directory = folderitem:WaitForChild("flashlight");
        name = "FLASHLIGHT";
        message = "CAN BE USED IN DARK PLACES";
    },
return data
