Hi Mike,
you're using the wrong syntax. Buses should consist of one ore more letters a rectangular bracket and the numbers of data lines including two dots between first and last number, e.g. D0 to D7 should have the netname D[0..7].
Using more signals e.g. D0 to D7, A0 to A14, SCK, SDL, VCC and GROUND the bus name should be "D[0..7],A[0..14],SCK,SDL,VCC,GND".
Don't use the space key when putting in the values and use a comma to separate items.
Always draw nets from the bus to the component pin. When starting a net a popup window will give you the selection e.g. D, A, SCK, SDL, VCC AND GND and one more window, e.g. D0 to D7 when selecting "D".
Take a look at the connector and the bus as attached.
Regards
