"Attempt to compare string and number" Help?

Working on a gui that is cloned to your playerGui if you are at or above a certain group rank. After testing, this should work, but still isnt. Both of the values shown are number values. No values here are string. This is a serverScript that is in serverScriptService. My code:

local groupId = script.GroupId.Value
local minimumRank = script.MinimumRank.Value

game.Players.PlayerAdded:Connect(function(player)
		if player:GetRoleInGroup(groupId) <= minimumRank then
			local guiClone = script.Announce:Clone()
			guiClone.Parent = player:WaitForChild("PlayerGui")
		end
end)

Any help would be appreciated.
