Updating multiselect lookup column in SP library

[ezuboy]

Hello All,

After obtaining a record of ID from the Join action I am unable to use it to update my library fields. The challenge is after getting the result from the join action (e.g 14,15) converting it to an array to plug it into the update file properties. The column is a multi-select lookup. 

Any help?
