I have searched the forum and while I have found some threads relating to this I can not find a definitive answer to my problem. Here is my issue: I have a multi-value parameter dropdown with 22 values, I have a column I want to be visible if any one of 3 values are selected (R82, R85 or R93). I have tried the following in the column side/hide properties =Iif(Parameters!TCN.Value(0) = "R82" OR Parameters!TCN.Value(0) = "R85" OR Parameters!TCN.Value(0) = "R93", False, True) This seems to work the best out of all the solutions I have found but it is not perfect. If a value in the the list before R82 is selected as well as R82, R85 or R93, the column remains hidden. If R82 or any of the other values above are the first selection in the list then the column is visible as required. I need the column to be visible when any of the 3 values above are selected regardless of any other values selected before of after them the drop down list.
