I need to create an "if statement" for the below result of a javascript calculation, however the "var ansD" variable won`t let me, any help would be appreciated,

var ansD = document.getElementById("result_price");
ansD.value = '' + Math.round ((val1 * val2 * val3*100/5000/100 + 15.00 * 1.50 +(val4 * 0.68))*(valq1))

Regards,
