[protege-discussion] Expressing complement in PAL in Protege 4.1

I'm trying to write a simple rule in the PAL swrl editor and can't figure
out why it won't let me.  I'm trying to write an expression where if a
service provider is not a low, middle or high income provider that they're
an allincomeLevel provider.  So I'm trying to use the complement of each.

Here's what I'm trying to do:

ServiceProvider(?x),  not LowIncomeLevel(?x), not MiddleIncomeLevel(?x), not
HighIncomeLevel(?x) -> AllIncomeLevels(?x)

Any help with this would be appreciated.
