Multi-row Variable Set - check for duplicates (or only accept unique values)

[JLeong]

Hi Guys,

Need help on Multi-row Variable Set. I only have one column (single text), but I need to make sure that user doesn't enter the same value over and over. 

I am doing it on a Catalog Client script. Please assist.

Thank you in advance.

Regards,

Jocelyn

@Hitoshi Ozawa were you able to make this work on Service Portal? We followed your onSubmit client script code on the MRVS but nothing happens. (We're in Paris as well)

parent.g_form is returning undefined.

If you're in Service Portal, that may be by design.  I'd suggesting opening a new post to ask your question. 
If you don't want to do that, can you share specifically what UI this is failing in UI15, UI16, Service Portal, Now Experience?

I have tried hozawa's idea in Service Portal.

In client script of MRVS, I am getting undefined for parent.g_form.

@hozawa , any inputs on this?

[Hitoshi Ozawa]

Will check.
