JS sequence count using web service array

    /*create a table with webservice provided objects ex Records*/
    function createTable(table, webSerArr, selectName){
        /*trying to find a way to make this more global -- not there yet*/

        /*for loop to add the rows*/
        for(var i = 0; i < webSerArr.length; i++){
            row = table.insertRow(i+1);

            /*The following creates cells and fills them with the required information*/
            row.insertCell(0).innerHTML =  (webSerArr.length-i) ;
            row.insertCell(1).innerHTML = webSerArr[i].clientno ;
            row.insertCell(2).innerHTML = webSerArr[i].clientname ;
            row.insertCell(3).innerHTML = createrow(table, webSerArr, selectName,i);
            row.insertCell(4).innerHTML = webSerArr[i].admdate ;
}


function createrow(table, webSerArr, selectName,i){
     var count=0;
     if( i==0 )
        return 1;
    else if( webSerArr[i-1].admdate!= webSerArr[i].admdate  ){ 
        return 1;
    }
    else if(webSerArr[i-1].admdate== webSerArr[i].admdate && count==0  ){
        count=count+1;
        return 1;
    }
    else if(  webSerArr[i-1].admdate== webSerArr[i].admdate && count==1){
        count=count+1;
        return 2;
    }
    else if( webSerArr[i-1].admdate!= webSerArr[i].admdate && count==2)
        return 3;
    }

function creattable(...) creates rows and fills them with values from webservice. the problem is in filling this row : "row.insertCell(3).innerHTML" I created a function "createrow(...)", as you see above, however the problem is that in each time we are calling this function the value of count will return to 0 and it is not updated. How is it possible to make count be updated, as required, after each call.

Note: (webSerArr[i].admdate: returns the admission date. On that base we are filling the values).

The problem is that you init the count variable every time the createrow function is called. Just initialize it outside of the function:

var count = 0;

function createrow(table, webSerArr, selectName,i){
     if( i==0 )
        return 1;
    else if( webSerArr[i-1].admdate!= webSerArr[i].admdate  ){ 
        return 1;
    }
    else if(webSerArr[i-1].admdate== webSerArr[i].admdate && count==0  ){
        count=count+1;
        return 1;
    }
    else if(  webSerArr[i-1].admdate== webSerArr[i].admdate && count==1){
        count=count+1;
        return 2;
    }
    else if( webSerArr[i-1].admdate!= webSerArr[i].admdate && count==2)
        return 3;
    }
}
