SQL Linking Multiple Sums to a select query

[Magic8Computing]

I have a couple of SQL databases that i am trying to link results from.

My first database is calendar that i need to return the details for today so current date and targets for sales and orders that works

my second data base is for orders which i can sum the total orders for today and add that to a column on the select statement (code below) but the trouble started when i want to add another column with total orders for the period so far using periodstartdate and currentdate from database 1. any help would be great

USE [FFP_WebServices]
GO
/****** Object:  StoredProcedure [dbo].[WEBSERV_DAILY_FIGURES_SELECT]    Script Date: 11/10/2018 11:14:11 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
