This doesn't seems correct. the sub_list is a field object in your code. What you need to actually do is getValue instead of getFields. Also, you don't need to assign new_sub_list the sub_list variable. instead, you should just declare it as an array using var new_sub_list = [];

thanks. so something like this? var item_record = record.load(currentRecord); var sub_list = item_record.getValue({ fieldId: 'subsidiary' }); var new_sub_list = [] for (var x in sub_list) { new_sub_list[x] } new_sub_list.push("4")

for (var x in sub_list) { new_sub_list.push(x); }

new_sub_list is not a function error

my bad. should be new_sub_list.push(x);

so code runs fine now without any error but my item's sub doesn't get updated with the new value...should we end using item_record.save(); or something else? thanks mate, just popping out for a bit!
