Need Help Debugging Formula

Hi everyone,

Since I am not very familiar with formulas in Monday.com, I would really appreciate your help.

I am currently working with a formula column on my board, but I keep getting an “unexpected error” when I try to use my formula. I believe the issue is in the formula itself, but I am not sure what’s wrong.

Here is the formula I using:

What I am trying to do is: “Take the FY End Date, add 157 days (5 months + 1 week) to it, and show the result in another column.”

Has anyone encounter into a similar issue, or could kindly take a look and help me spot what’s going wrong?

Any help or suggestions would be greatly appreciated!
Thanks in advance!!!
