How do we compare two Record Permission fields?

[JaganChandrava1]

Need to compare two different Record Permission fields. If both the values are same, then we need to blank the 2nd field. Else the same value.

How could we get this via custom code?

Is this what your question is? 

If X = Y, 

Then Y = blank,

Else Y = X?

Why would you do this? It is a continuous rotation of a blanking Y and making it equal X just to blank Y again.

Or am I missing something?

Hi Rob Wilder‌,

X and Y are User editable fields.

If X = Y,

Then Y= Blank,

Else Y=User entering value.
