The script don't work

" Variable 'Categories_>' is n:1 relationship ";
let catg := 'Categories_>';
let rate := (select Categories where Category = catg).Rate;
'Rate by Categ' = rate

I try once choose the 'Categories_>' automatically give me the rate on the field 'Rate by Categ'.

I place the script in trigger After Update.

    Hi  You need to add a first() function in your select statement to return a record rather than an array

    let rate := first(select Categories where Category = catg).Rate;

      Hi John Thanks, no work, the 'Categories_>' is a N:1 Relationship , and I'm on Table  'Hours by Resources'.

    'Rate by Categ' = rate

    to be

    'Rate by Categ' := rate

    If I am understanding this correctly and Categories is the table and Categories_> is the relationship you can just use

    Categories_>.Rate

    Either assign this to Rate by Categ or use is as is and don't use Categ at all and then you won't need a trigger.

    I like your _> and <_ notation by the way!

    Regards John
