I currently have a subform and I would like to automatically display (like default value) the 'PU' from (temporary Table) in 'Prix Unitaire' as soon as I choose an article by lookup from 'ARTICLE' in (temporary table).
and also check the quantity entered if less than or equal to the quantity in stock (<= 'SOLDE' in temporary table).
I need help

I tried with this --> nuSetFormValue('des_prix',nuLookupRecord()->PU); but the field 'Prix Unitaire' still blank
