I have a function that sums the values of a column of data that works fine if I change the values of one of the columns. That same function is being called when the page loads but no values are returned so that the sum is zero. I am using Google Chrome so that I can write to the console and I see that the input fields that I am wanting to sum are being captured. When I drill down on each input field I can also see that the value of each field is present. Why is that value not being returned on page load? Below is the function;

 

function sumOfActualColumns(tableID, columnIndex, hasHeader) {

      var actualTot = 0;

      $( "#" + tableID + " tr" + (hasHeader ? ":gt(0)" : "" ))

      .children( "td:nth-child(" + columnIndex + ")" )

      .each( function () {

            thisActualVal = $( this ).children( 'input[id*="ActualsTotal"]' ).val().replace(/[^\d\.\-\ ]/g, '' );

            thisActualVal = Number(thisActualVal);

            if (!isNaN(thisActualVal))

                  actualTot += thisActualVal;

          });       return actualTot;

}
