how can i do this

Insert a new formula field, call it the name you like
Inside the formula editor, write

Code:

---

If {TableName.FieldName}=1 Then "Cash" Else
If {TableName.FieldName}=2 Then "CC" Else "Other"

---

After that, place the formula in the desired rpt section
Note: Replace TableName and FielName with real ones
Here we are assuming that the field is numeric type
