Error NaN when trying to add two input fields in Javascript
I am trying to sum two text fields using Javascript and my result keeps coming back as NaN (not a number?) and I am entering only numbers in the input fields. Despite some debugging in Visual Studio, I still can't figure out why?
Here is my HTML code:
<div id="calc"> <p> <label for="num1">Enter Your First Number:</label> <input type="text" name="txtNum1" id="txtNum1" size="5" /> </p> <p> <label for="num1">Enter Your Second Number:</label> <input type="text" name="txtNum2" id="txtNum2" size="5" /> </p> <input type="button" name="add" id="add" value="Add" onclick="addNum();" /> </div> <div id="ShowResults"></div>
