Problem with LPM_MUX

This is a basic problem but it is catching me out, I am trying to implement a simple 2-to-1 mux using the LPM but Quartus is kindly telling me I am using the 2D_std_logic type incorrectly mux...

there is no such thing as a 2D_std_logic type. You also cannot index DATA like you have (it is illegal VHDL)

Did you generate the mux via the megawizard? or are you trying to do it manually?
