LM5067QUICK-CALC: i am facing LM5060 simulations error

Part Number: LM5067QUICK-CALC
Other Parts Discussed in Thread: LM5060

Hello,

I am simulating the LM5060 in LTspice . Trying get boost voltage by following application circuit and input is 48V,However, I am getting the following error: 

My goal is to implement a gate driver that outputs or boost more than input supply ( more than 50 and less than 65V)

Error:

Questionable use of curly braces in "b§e_abmgate yint 0 v={if(v(a)>{{vthresh}},{{vss}},{{vdd}})}"
    Error: undefined symbol in: "if([v](a)>((vthresh)),((vss)),((vdd)))"
