Why doesn't the studio recognize this as equal?

No one on the Roblox forum has answered this and I can't continue working on my place until it's figured out.

For some odd reason the studio doesn't read two of my variables, which have identical values, as equal. What happens is a player clicks on a brick, and a simple addition problem appears in their player gui. They can type in the answer on the gui and check the answer with a button.

function onClicked(p)

    script.Parent.Number1.Value = math.random(1,5)
    script.Parent.Number2.Value = math.random(1,5)


    local var1 = script.Parent.Number1.Value
    local var2 = script.Parent.Number2.Value

    wait(1) --Needs to wait so other script can check for current Gui's and destroy them

    Instance.new("ScreenGui",p.PlayerGui)
    local g = p.PlayerGui.ScreenGui

    Instance.new("Frame",g)
    local f = g.Frame
    f.Name = "Box"
    f.Size = UDim2.new(0,300,0,50)
    f.Position = UDim2.new(0.5,0,0.5,0)

    Instance.new("TextLabel",g)
    local n1 = g.TextLabel
    n1.Name = "Number1"
    n1.Size = UDim2.new(0,30,0,30)
    n1.Position = UDim2.new(0.52,0,0.52,0)
    n1.FontSize = "Size36"
    n1.Text = var1
    n1.BorderSizePixel = "0"

    Instance.new("TextLabel",g)
    local n2 = g.TextLabel
    n2.Name = "Number2"
    n2.Size = UDim2.new(0,30,0,30)
    n2.Position = UDim2.new(0.52,100,0.52,0)
    n2.FontSize = "Size36"
    n2.Text = var2
    n2.BorderSizePixel = "0"

    Instance.new("TextLabel",g)
    local p = g.TextLabel
    p.Name = "PlusSign"
    p.Size = UDim2.new(0,30,0,30)
    p.Position = UDim2.new(0.52,50,0.52,0)
    p.FontSize = "Size36"
    p.Text = "+"
    p.BorderSizePixel = "0"

    Instance.new("TextLabel",g)
    local e = g.TextLabel
    e.Name = "EqualSign"
    e.Size = UDim2.new(0,30,0,30)
    e.Position = UDim2.new(0.52,150,0.52,0)
    e.FontSize = "Size36"
    e.Text = "="
    e.BorderSizePixel = "0"

    Instance.new("TextBox",g)
    local a = g.TextBox
    a.Name = "Answer"
    a.Size = UDim2.new(0,30,0,30)
    a.Position = UDim2.new(0.52,200,0.52,0)
    a.FontSize = "Size36"
    a.Text = "?"
    a.BorderSizePixel = "0"

    Instance.new("NumberValue",a)
    local value = a.Value
    value.Name = "InputValue"
    value.Value = value.Parent.Text

    Instance.new("TextButton",g)
    local check = g.TextButton
    check.Name = "Check"
    check.Size = UDim2.new(0,300,0,25)
    check.Position = UDim2.new(0.50,0,0.50,50)

    Instance.new("NumberValue",g)
    local needed = g.Value
    needed.Name = "CorrectAnswer"
    needed.Value = var1 + var2

    local answer = game.Workspace.Answer:Clone()
    answer.Parent = needed


    print(g)
    print(f)
end

script.Parent.ClickDetector.MouseClick:connect(onClicked)

The button has a script which, when clicked, checks the two numbers being added, what the answer should be, and what the answer typed is. All the prints were for finding out where my script was going wrong.

function check()
    local input = script.Parent.Parent.Answer.Text --the answer typed
    local inputvalue = script.Parent.Parent.Answer.InputValue.Value --IntValue
    print("The input is "..input..".")
    print("The value is "..inputvalue..".")

    inputvalue = input --IntValue becomes the answer typed
    print("The updated value is "..inputvalue..".")

    local correct = script.Parent.Value --what the answer should be
    print("Current inputvalue is "..inputvalue..".")
    print("Answer should be "..correct..".")

    if inputvalue == correct then --Here is the issue
        print("Correct!")
        print(""..inputvalue.." = "..correct.."")
    else
        print("Incorrect!")
        print(""..inputvalue.." ~= "..correct.."")
    end
end

script.Parent.Parent.Check.MouseButton1Click:connect(check)

For some reason, even when the print command tells me 'inputvalue' and 'correct' are identical numbers, the if function say's their false. Also, if I put:

if inputvalue == input then

as I stated earlier in the script, then the if function works fine. For some reason the script thinks the variable 'correct' isn't identical to 'inputvalue' despite the print command returning the exact number for help.
