Yes you can but remember that a textbox does not repeat like a detail table.
Here's how you do it. Right click your textbox and choose expression.
Code:
="Good morning, " & First(Fields!Name.Value, "Dataset_Name") & "."
& " Here is " & First(Fields!Money.Value, "Dataset_name") & " for you."
Output will be in the textbox "Good morning, George. Here is $5.00 for you." Let me know if you have any questions.
