I have a list where I have a look up field with allow multiple values. Now, I would like to get the IDs of this look up field into a collection. My workflow is acting on the list where look up field is used. The reason I would like to achieve this is that, I would like to fetch other values of these look up field values (other columns I mean) and do some math on them and set the value in the current list to this sum.
Please advise how to achieve this using Nintex workflow.
Thanks in advance,
