Microsoft JScript runtime error: Unexpected quantifier

   Hi,
   
    Microsoft JScript runtime error: Unexpected quantifier

    this error tells that, When composing your regular expression search pattern, you created a pattern element with an illegal repetition factor. For example, the pattern

              /^+/

  is illegal because the element ^ (beginning of input) cannot have a repetition factor. The following elements that cannot have repetition factors.   

    ^, +, *, $, \b, \B, ?, {n}, {n,}, {n,m} 
 
    where {n} for  n repetitions
            {n,} for  n or more repetitions
        {n,m} for From n to m repetitions, inclusive 

  
  Thanks
   hope this will help you
