Can you Automatically Update Formulas and Data Validation Between 2 cells in Excel Using VBA

[Saud_Jilani]

In Excel, I have the following formula in cell D14:


=LET(
lookupValue, $D$13,
Name, VLOOKUP(lookupValue, Cust_Tbl, 2, 0),
IF(lookupValue<>"", IF(Name<>"", Name, ""), "")
)

This formula returns the name based on the contact entered in D13. I now want to extend this functionality, so that I can enter a name in D14, and the corresponding contact will appear in D13 using the lookup. Is it possible to achieve?



I want to automate this process using VBA. Specifically, if I make a change in D13, the formula in D14 should turn into searching. Similarly, if I make a change in D14, the formula in D13 should adjust accordingly.

Additionally, I have data validation applied to D13 with the formula '=Cust_List'. So, I also want the data validation in D14 to change to '=Cust_List_Name' when it will be used for search.
