Fix matrix column and IF-ELSE statement

Hello.
I have to questions -
1) I have a matrix in my report and I want The group column to be fixso if I have a lot of columns and I scroll left the Header column willstay in the left of the screen and only the result column will bescrolled.
How can I do it?
2) How can I use a IF-ELSE statment or a CASE in the expression?
I want one of my column to be red if the value is "1", green if the value is "2" and blue if the value is "3".
Is there a way to do it?

Thanks in advance.Just to let you know that I found a replacment for the if.

I found that there is a switch-case statment in SSRS :)

I still be happy to hear if there is a way to make the first column ofa matrix or table fix (like in excel) so they will stay visible even ifI scroll left or right.

Thanks.|||

O.k so I got the answer to this matrix thing too.

After creating a column group you can use (in the "edit group" option) the "Group header should remain visible when scrolling" and thats what make the magic happen.

Thanks to andy for the solution :)

take care,
