Quartus II mux for schematic entry?

Sorry for the newbie question:

I have Quartus II 4.2 Web edition.

I don't see a multiplexer symbol in the Quartus library, unless I open the Max II folder. Ok to use the Max II 74 series libraries?

Thanks

    Hmm. No design files for MaxPlus logic cells.

    Guess I have to make a mux from AND and OR gates?

    Clancy:

    I placed "BUSMUX" into my desgn. I set the "width" parameter to 8, then double clicked on the mux icon, error message says:

    Can't locate design file for entry "BUSMUX"

    Use lpm_mux.

    Make sure you have "Launch MegaWizard Plug-In" check box selected.

    Press OK.

    Select your HDL language (it will autogenerate a wrapper in the language you select).

    Press Next and enter the mux parameters. Continue to Finish.

    I hope this helps :)

    Always use lpm_ library components if available.
