Hi alhowarthWF,
If your MnthYr parameter is a datetime, this is simple.
Otherwise, you will have to do some string parsing, as the string 2021-08 is not a standard date.
You could try this function:
="This report is for the month "
+ Switch
(
Right(Parameters!MnthYr.Value,2) = "01", "January",
Right(Parameters!MnthYr.Value,2) = "02", "February",
Right(Parameters!MnthYr.Value,2) = "03", "March",
Right(Parameters!MnthYr.Value,2) = "04", "April",
Right(Parameters!MnthYr.Value,2) = "05", "May",
Right(Parameters!MnthYr.Value,2) = "06", "June",
Right(Parameters!MnthYr.Value,2) = "07", "July",
Right(Parameters!MnthYr.Value,2) = "08", "August",
Right(Parameters!MnthYr.Value,2) = "09", "September",
Right(Parameters!MnthYr.Value,2) = "10", "October",
Right(Parameters!MnthYr.Value,2) = "11", "November",
Right(Parameters!MnthYr.Value,2) = "12", "December",
True, ""
) + ", "
+ Left(Parameters!MnthYr.Value,4)
Just place the above code snippet into your text box.
I hope this helps.
