Question

我需要一项活动的帮助。我不断得到同样的错误，因为我不明白为什么会这样。

这是问题，我得到的错误和我的代码。

        var purchases; // purchase

        salesTax = prompt("Enter your total amount of salesTax: ", ES);
        salesTax = parseFloat(salesTax);

        // calculate

        if(salesTax <=0)

else if (salesTax<=64) {
    document.write("4 cents tax." + BR);
}
