Validating date period

[sugoi_kat]

The user can view a report during a specific period by specifying the starting and ending date. What I want to do is check that the ending date of the period they specify isn't less than the start date. The code below is the current function i'm using to check that the period is valid. It takes values from the textbox on the page and compares the two dates and if the starting period is greater than the ending period, then an alert message appears. However, it doesn't seem to work. Am I doing this correctly?

function checkDate(){    var dStart = document.stu_comp_ex_report.startDt.value;    var dEnd = document.stu_comp_ex_report.endDt.value;    if (dStart > dEnd)     {        window.alert("Make sure the start period is before the ending period");    }    else    }        if (dStart = null || dEnd = null)        {            window.alert("Please ensure that the starting period and the ending period are stated");        }    }}
