Title

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.
