How to use VALUES with other filters?

[hemingt]

Hello 

I have a table named Tasks, and there are several columns, and two columns named 'Week' and 'FixVersion'

I want to firstly filter the table according to the column FixVersion with the condition Filter(Task, Task[FixVersion]=SELECTEDVALUE(Task[FixVersion])), then get the unquine with VALUES(Task[Week])

Do you know how to do? Thank you very much!
