Stored Procedure Not Returning Value

Trying to get a count on records that match search and all I'm getting is 0. I'm using the same basic sp and code elsewhere and it works fine. Anyone see anything wrong here?

Stored Procedure:
CREATE PROCEDURE GetResultsCount
(
@searchCatalog nVarchar(100)
)
AS
RETURN ( SELECT COUNT(*) FROM Catalog
WHERE itemName LIKE @searchCatalog OR
itemLongDesc LIKE @searchCatalog
)
GO

Code:
        Dim connStr As SqlConnection
        Dim cmdResultsCount As SqlCommand
        Dim paramReturnCount As SqlParameter
        Dim intResultsCount As Integer
        connStr = New SqlConnection(ConfigurationSettings.AppSettings("sqlCon.ConnectionString"))
        cmdResultsCount = New SqlCommand("GetResultsCount", connStr)
        cmdResultsCount.CommandType = CommandType.StoredProcedure
        cmdResultsCount.Parameters.Add("@searchCatalog", Request.QueryString("search"))
        paramReturnCount = cmdResultsCount.Parameters.Add("ReturnValue", SqlDbType.Int)
        paramReturnCount.Direction = ParameterDirection.ReturnValue
        connStr.Open()
        cmdResultsCount.ExecuteNonQuery()
        intResultsCount = cmdResultsCount.Parameters("ReturnValue").Value
        connStr.Close()
        Me.lblResultsCount.Text = intResultsCount
