SSRS passing multiple values parameter

Hi ,

I have a multi select parameter that get values from a query in my SSRS report. The report works fine if i select a single value in drop down list. When trying to select All or select a multiple value i got an error. Any help is very much appreciated. thank you.

By the way, i'm using Query type text not an stored procedure.

Data in my @LineID parameter drop down list

Select All

Line1

Line2

Line3

up to Line15

I tried this approach and its not working. In dataset properties under parameter value expression, i made this approach

=Join(parameter!Lineid.value,",") or =parameter!Lineid.value

My Query:

Select * from sample
Where pt.Asuprodlineid IN (@LineID)
