Not able to memorize domain spells

[Trillarel]

I am a cleric of Lolth. In my 'spells', spider climb shows up as domain. I have an empty domain slot. (Level 1 spells are 5/6)

I type 'rest', then:
mem 'spider climb'

and invariably, it tells me
'You do not know that spell.'

The correct syntax for memorizing domain spells would be 'memo domain (spell name)'

So, memo domain spider climb. And without the quotation marks.

Don't forget to check helpfiles before making a bug report. :)

Spell Memorisation
==================
Syntax: memorise (or just 'mem')
memorise <spell name>
memorise [number of instances to memorise] <spell name>
mem [instances] [effective level (to apply metamagic)] <spell name>
memorise domain <spell name>
