Populate columns with row values in Sql Server Reporting Services

I have got a dataset with 2 columns named Row and Title. There are 8 rows in this dataset and I want to display those 8 titles within columns in a table. So I create a table with 8 columns and set each column's expression to

=LookUp(Fields!Row.Value,1,Fields!Title.Value,"Titles")    
=LookUp(Fields!Row.Value,2,Fields!Title.Value,"Titles") 
=LookUp(Fields!Row.Value,3,Fields!Title.Value,"Titles") 
.
.

However only the first column displays a title. The other 7 display nothing. Is my expression wrong?
