If, &, OR Functions in expressions

Hello,

I'm making a design with supress by an expression.

I know in SolidWorks there is an option to make an equation, with OR in it

like this;

IF ("bolts" = 0 OR "number_of_extra_bolts" < 1, "suppressed", "unsuppresed"

I want to do the same thing in NX9, I'm already using& functions, like this, but I want it like an OR function like in solidworks

if("V608673/AA"::number_of_extra_bolts<1 & "V608673/AA"::bolts=false) (0)else(1)

Can somebody help me?
