<form autocomplete=on>

<p/>

<label>Year</label>

<input type=text id=year name=year autofocus/>

<p/>

<label>Month</label>

<input type=text name=month id=month />

<p/>

</form>

<input type=button onClick=method() />

JavaScript

function method(){

var year = document.getElementById(year).value;

var month = document.getElementById(month).value;

var data = new Date(year,month-1,1);

var dataTable = document.getElementById(table);

var cells = dataTable.querySelectorAll(td);

var cells2 = dataTable.querySelectorAll(td+td);



for (var i = 0; i < cells.length; i++){

    var mikro = cells[i].firstChild.data.split(-);

    var place = cells2[i].firstChild.data;

    var firstData = mikro[0].split(.);

    var secondData = mikro[1].split(.);

    var data1 = new Date(firstData[0],firstData[1]-1,1);

    var data2 = new Date(secondData[0],secondData[1]-1,1);

    if(data1<=data && data2>=data){     

        alert(place);

        }

    }

}

Here i have 2 columns in the table, i want to create script which will help me to find information from it: I have <input type=text id=year name=year autofocus/> and <input type=text name=month id=month /> where i can enter year & month.After entering year&month i have to get information from the 2nd column according to the dates on the 1st column for example: Input year: 2002, Input month:05 - result must be 'Secondary School' because it between 1999.09-2007.06 . I can't see what is wrong with my script, it always give me false information.
