Studio Spot 250 Macros

I have a very strong suspicion this should be obvious but i'll also admit that im stumped.
I have a pair of studio spot 250s on my hog III PC. according to the manual, macro 2 is a ballyhoo, which i want, but i cannot (for whatever reason) activate it
I select the 2 spots in the groups window, on my screen below that are 5 buttons
colour
strobe
Gobo
gobo2
macro
i hit macro
a second button bar pops up with the following
none
one
two
three
four
i choose 2
and nothin happes
Can someone shed some light on what im doing wrong?
