      calculation for expiry & retest date

      Post

      Hello to everyone,

      I have six(6) fields

      1. Material Name

      2. Material Lot No.

      3. Expiry Date

      4. Retest Date

      5. Supplier

      6. Supplier Lot No.

      Can you help me make a calculation so that the user cant go to the fourth and fifth field if Expiry Date is Empty OR Retest Date is empty.

      Thank you very much in advance.
