I'm working on a project and I want to use the following function to check if the user has filled out the needed steps:

Code:
function stepCheck() {
if (!(document.OnlineForm.cardoption[0].checked == true || document.OnlineForm.cardoption[1].checked == true))
alert("Please Select A Payment Option Under Billing Info.");
}else if(!(document.OnlineForm.shipping[0].checked == true || document.OnlineForm.shipping[1].checked == true || OnlineForm.shipping[2].checked == true)){
alert("Please Select A Shipping Option.");
}else if(!(document.OnlineForum.tou.value == true)){
alert("Please Accept The Terms of Use.");
}
When I load it, I get a 'Syntax Error' message on the first 'else if' statement

all help is appreciated, thanks
