IF EQUALS Query in Report Builder

I am using Microsoft SQL Server Report Builder 3.0.I have a table called "tblDataPermit"My DataSet1 includes the column "Type"The Type column has numeric values 1-54. In my report if I use the Expression =First(Fields!Type.Value, "DataSet1") it will show me the numeric value in the Type column. I need my report to convert this value to a word, such as:If Type = 1 Then "One"If Type = 2 Then "Two"I have struggled with SELECT and CASE but am stuck. Thank you in advance for any assistance you can offer.
