SyntaxError: syntax error 6: at line 7 (multiple condition statement)

I have a pdf that contains three fields. One is a text field in which dollar amount is entered, the second is a text field in which a term is entered (i.e., 36, 48, 60) and the last field is the one in which the solved amount will be listed. An example of this formula is if Cost of Licenses >$25,000; multiple the entered amount * .03081 if  FinanceTerm = 36.

I'm getting the following error message: SyntaxError: syntax error 6: at line 7. I'm very new to multiple options and can't figure out what I'm missing. Any help is appreciated.

var A = this.getField("CostofLicenses").value; // the value of field A;

var B = this.getField("FinanceTerm").value; // the value of field B;

var C = this.getField("MonthlyPayment").value; // the value of field C;

event.value = "";

if(A>$24,999,B=="36"){event.value=A*.03081};

else if(A<$25,000,B=="36"){event.value=A*.03110};

else if(A>$24,999,B=="48"){event.value=A*.02383};

else if(A<$25,000,B=="48"){event.value=A*.02386};

else if(A>$24,999,B=="60"){event.value=A*.01962};

else if(A<$25,000,B=="60"){event.value=A*.01972};
