No Operator = Matches Operands - DX11

I'm trying to multiply two sets of values together in DX11.

void Update()
{
    rot += 0.0005f;
    if (rot > 6.26f)
        rot = 0.0f;

    cube1 = XMMatrixIdentity();

    XMVECTOR rotaxis = XMVectorSet(0.0f, 1.0f, 0.0f, 0.0f);
    Rotation = (rotaxis, rot);
    Translation = XMMatrixTranslation(0.0f, 0.0f, 4.0f);

    cube1 = Translation * Rotation;
    cube2 = XMMatrixIdentity();

    Rotation = XMMatrixRotationAxis(rotaxis, -rot);
    Scale = XMMatrixScaling(1.3f, 1.3f, 1.3f);

    cube2 = Rotation * Scale;

But I keep getting the error;

[code]No operator "=" matches these operands
operand types are: DirectX::XMVECTOR = DirectX::XMMATRIX[/code]

From what I have read, they can't be multiplied together, but I cannot seem to find a workaround.

Code Snippets.

Forward Declarations

const int Width = 300;
const int Height = 300;

XMMATRIX WVP;
XMMATRIX cube1;
XMMATRIX cube2;
XMMATRIX camView;
XMMATRIX camProjection;

XMVECTOR camPosition;
XMVECTOR camTarget;
XMVECTOR camUp;

XMVECTOR Rotation;
XMVECTOR Scale;
XMVECTOR Translation;
float rot = 0.1f;

Setting camera/projection at the end of the InitDevice() Function.

camPosition = XMVectorSet(0.0f, 3.0f, -8.0f, 0.0f);
camTarget = XMVectorSet(0.0f, 0.0f, 0.0f, 0.0f);
camUp = XMVectorSet(0.0f, 1.0f, 0.0f, 0.0f);
camView = XMMatrixLookAtLH(camPosition, camTarget, camUp);
camProjection = XMMatrixPerspectiveFovLH(0.4f*3.14f, Width / Height, 1.0f, 1000.0f);
