Self cast problem.

[Rhuiin]

I am very new to EQ2, so I am not sure what I am doing wrong. I assume that in the self window, where I see the icons for Cure buttons that I should be able to click those and cause spells to fire. However, when I click the buttons nothing seems to happen.

I am a paladin. So for example, with the 'Trauma' button, I want to assign it to cast 'Holy Aid II'. So I opened the interface and replaced the 'Cure' in the default line to: Holy Aid II. Thus it reads as follows:

useabilityonplayer MYSELF Holy Aid II

However, when I click that button, nothing happens. I have even tried just putting in a 'say' macro, but still nothing happens. When I click, I can hear a 'click' noise, but get nothing.

Am I totally misunderstanding the use of these buttons?
