Hi I would like to have one counter field which will be incrementing by 1 and at perticular time inverwal the field value would get reset and increment again by 1.Any suggestion please

Johib,
Sorry, but you will need to be much more specific.
You say that the counter starts when the record is entered.  Then are you wanting to count days?  Then are you saying that is resets back to zero every April 1st.  Please take the time to clearly express your question.  Often taking to the time to clearly express the question, leads to the answer.
