Do not update a lookup


How can I make a value entered through a “lookup” not be updated ?
That is, if the source value of the lookup changes, do not change the value of the linked field.
Thank you for your help and patience with a beginner like me.


You really can’t – a lookup field always and only reflects the value of the field you are telling it to lookup.

The only real work-around I can think if is to make another static text field next to the lookup field and copy-paste the value from the lookup into the static text field when it makes its initial lookup (it’s initial state). Then, while the lookup will change when it’s referenced field changes, your static text field next to it will not change.
