Gear Buff Macro Not Working

[Nelenarap]

Trying to use the Gear Buff Macro function, but can't seem to get it to work. Starting with the earring of the Solstice for it's run speed buff. I think I have it setup right. Looked up the Item ID via eq2wire. The DarqUI Help area says to use the utility, but I can't find an area of the utility for this purpose. I'm wanting to equip the item, cast the buff, and then re-equip my original earring.
