Question

Hello just wondering why firbug is stating NaN even when these inputs have information entered.

    for(i=1;i<8;i++){
var field = document.ContactForm.Field + i.value;
console.log(field);

    }

i am trying to iterate through field1, field2 field3 …. field7.

Answer 1

I assume you have a number of fields Field0 … Field8.

For that, you need to use different notation:

var field = document.ContactForm[Field + i].value;

by the way, while forms can be accessed by name the way you show, a more preferable approach would be the document.forms array:

 var field = document.forms["ContactForm"]["Field" + i].value;
