    Java Script Problem

    I have a javascript problem. I wish someone can solve it.
    I have a combobox where it displays string values.
    I have an unique id for each of the string values which is an integer.

    I am using form1.object.op tions[form1.object.se lectedIndex].id*1; so I
    can get the correct id for the selected string. This works fine for
    me.

    But in another combo I need to have the id as a 'String' not as an
    integer,
    for this the above javascript doesnt work. It returns an 'NaN'

    Please tell me how can I get the string id for the selected value.

    Any help is greatly appreciated

    Thanks
    Shiran.

          Drop off the "*1". It is only there to convert the string value to a
          number. If the string does not contain a number, trying to convert it
          gives NaN (Not a Number).

              To avoid convertion problems with strings that start with '0' (treated
              as octals) you should specify the radix:

              parseInt(intege r, 10)

              I hope this helps.
