    Hi Divya,

    You get that error because the string field might have something else other than numbers too.

    For e.g.: A string field with this value : 12345Abhilash*^%, cannot be converted to a number.

    You would need to extract the numbers from the string.

    Use this instead of tonumber():


    Hope this helps!
