Stored Procedure Output Value Not Updating - sql

Question

Everyone.
I have created a stored procedure in SQL Server 2016 that has the purpose of giving the of the total number of sales recommendations [#Recommendation in Recommendations table] in my table that contain this string: '____Document DOB in sales record' past any given date. I want to put this result into a temporary table as well.
Helpful Table Info:
Reference Table where I am grabbing the data: Recommendations
The relevant fields in the Recommendations table are #Recommendation, and #SalesProcessTime
The #Recommendation field is a VARCHAR(255), and #SalesProcessTime is a DATETIME
Regardless of what I change the date to - or even if I make it =, >=, etc - the same numeric value is displayed.
If you need anything else, please don't hesitate to ask me.

-- Count of the number of recommendations
SELECT #NumRecs = COUNT(Recommendation)
FROM [Master_AGGREGATE].[dbo].[Recommendations]​
WHERE Recommendation = '____Document DOB in pt record' ​
and SalesProcessTime > '2018-10-20'
CREATE TABLE ##RefCount (NumberOfRecs INT);
INSERT INTO ##RefCount
SELECT #NumRecs
END
EXEC usp_SalesRefCount
SELECT * FROM ##DocDOB

Answer 1

Why are you using a global temporary table at all? Why not just return the results from the procedure directly? eg:
CREATE PROCEDURE usp_SalesRefCount
AS
BEGIN
DECLARE #NumRecs INT;
SELECT #NumRecs = COUNT(Recommendation)
FROM [Master_AGGREGATE].[dbo].[Recommendations]​
WHERE Recommendation = '____Document DOB in pt record' ​
and SalesProcessTime > '2018-10-20'
SELECT #NumRecs NumRecs
END

Answer 2

You are inserting data into a global temporary table "##RefCount" and selecting from another one "##DocDOB", so the result will never change.
Anyway, as #DavidBrowne said, you should just return the result directly
CREATE PROCEDURE usp_SalesRefCount
AS
BEGIN
SELECT COUNT(Recommendation)
FROM [Master_AGGREGATE].[dbo].[Recommendations]​
WHERE Recommendation = '____Document DOB in pt record' ​
and SalesProcessTime > '2018-10-20'
END
Also, another idea, maybe get that date as a parameter, so you don't have to update the stored procedure when you need to select by another date
CREATE PROCEDURE usp_SalesRefCount
#selectDate DateTime
AS
BEGIN
SELECT COUNT(Recommendation)
FROM [Master_AGGREGATE].[dbo].[Recommendations]​
WHERE Recommendation = '____Document DOB in pt record' ​
and SalesProcessTime > #selectDate
END
