swing eighths in

[Donald J. Stewart]

I'd like to set something similar to 'eighth note = triplet' (attached tempo 
marking)

I see 'Beat Change' under Directives -> Markings -> Tempi and Metronome marks

But for some reason I get an 'unable to typeset' warning when I attempt to use 
this.

I'm sure there's a simple solution that I'm just overlooking...
