Help please I have encounted another problem in the result, for some reason my function is not recognizing double (or greater) digit numbers it converts them to single digits e.g “23 4 55” it converts to “2+3+4+5+5=19” and not “23+4+55=82”

function calc() {
// calc() is designed to sum numbers entered in an input field
var t = document.getElementById(“num”).value; // the numbers entered
var numbers = new Array();
numbers = t.split(/s*/); // the numbers extracted from the string
var sum = 0; // variable to hold the sum of the numbers
var num = ”; // string to hold a list of the numbers
if (numbers.length == 1) { num = ‘0’; } // to add single number to
for (i = 0; i < numbers.length; i++) {
sum = sum + eval(numbers[i]); // add this number
if (i == numbers.length – 1) { num = num + ” and “;} // last number?
else { if (i > 0) { num = num + “, “} } // otherwise if not 1st, join with ,
num = num + numbers[i]; // and add the number to the list
}
// create the text to display with the result
result = “<p>The sum of the numbers ” + num + ” is ” + sum +”<“+”/p>”;
// find the placeholder for displaying the result
var resElement = document.getElementById(“res”);
// display the result
resElement.innerHTML = result;

<!– provide a dummy button – encourage user to leave input tag –>
<input type=”button” value=”Calc”>
<!– the following div id=’res’ provides a placeholder
that calc() can use to display the result –>
