What I did now is that I just put in a single digit for the month, I mean for example I intend to key in January, I just put in the number 1 and made sure that I dont make any overlaps and it work! I am able to successfully validated the form just now.We had the same problem. It was because we had some overlap. I put in my wifes part time jobs. The file won't allow you to validate if you were doing two things at one time.
