I've got a catalogue item that allows a user to not select a certain field and they can leave this empty:
From the screenshot, the user can leave the New Lab Level/Platform Child field empty. However, when a user submits their request, it appears as NULL in the requested item rather than showing as empty:
I'm using a multi row variable set to get my results. The following client scripts apply to the New Platform and New Lab Level/Platform Child fields:
Does anyone know what I need to do to show New Lab Level/Platform Child field as an empty value on my requested item rather than null

Hello @matthew_hughes
Directly updating the variable is not available in flow, but you can create a custom action (reusable) to update the variables.
Thank you,

Hi @Ahmmed Ali I tried creating the action in the example, but it won't allow me to select affected variable within my multi row variable set

Hello @matthew_hughes
You will need to create custom action particularly for your item, means have input as RITM sys_id. then in script activity, query RITM table and set variable value or you can query sc_multi_row_question_answer table and update accordingly.
Thank you,

If you change this line
g_form.clearValue('new_lab_department');
to this
g_form.setValue('new_lab_department', '');
Does that make a difference?
