Creating hyperlink to "created" folder - Sharepoint 2013 Workflow

Hello,

I have a DocumentLibary and a TaskList. Inside TaskList i have a column called DocumentHyperlink. What i would like to achieve using a workflow is to:

1. User creates new task

2. Folder witch the same name as task name is created

3.  For the task user just created, update the DocumentHyperlink with the hyperlink to the folder created in step 2. 

So far i manged to update the filed with a link to the DocyumentLibrary. When i try to use something like this: 

http://server/site/DocumentLibrary/[%Current Item:ID%]/, Folder

this is exactly what i am getting in the filed... 

Can you please advice? 

Thank you in advance!
