Ommitted the quotes on "1+0"

but still 1+0=1
.... couldn't resist, sorry
Didn't think of it as normally I do not select B to OVRD and bear with the Slat Fault indication - which contravenes the FCOM 2 procedure as I learned today. Thanks anyway!!!
Nice rule of thumb I forgot to use before asking is to write the system colours alphabetically and then imagine a wing devices profile: BBG-GYY
front -> slats -> B&G, aft -> flaps > G&Y.
No G or Y, no flaps. Need to think harder next time.
