Remove Duplicate Column Values in Complex Join Query

I have the attached query working;
I am trying to display the grid in the attached image.
This is a grid of fuel pump readings from one day to the previous day so i join the table to itself.
Most of the fields that I need are in one table so that part is OK.

Next, I need to join another table to pick up the deliveries for a particular date in the grid.
This will mostly be just one day in the range.
However, when I join the table I get an entire column of the same values; when I would simply like to show the value for the particular day.
Image 13 shows the duplicates I am getting in the GALLONS DELIVERED column (quantity_received_fw); and Image 14 shows what I would like to get - the one delivery for the particular date: in this case, 5999.00 for 8/2/2010;
My attached query here is hard-coded to show output-
How can I write this query to ONLY get the ONE delivery value for the particular day?
thanks  13 14

Hi,

If we suppose that one table X contains delivery quantity, delivery date and tank_id, you must have a left join as this :

left joint Delivery_Table on  
ON v.TANK_ID_FW= X.Tank_Id
and v.transaction_date_fw = Delivery_Date

hi-
thanks; this seems to work;
one last thing...
i need to sum the column of total gallons pumped;
can you help with this?
currently, i am using this as a stored procedure to a reporting services report.
i simply add a footer and put the sum in there;
but, i also want to display the sum elsewhere on the report.
can you help?
thanks.

you can do a :
select sum(GallonsPumped) from (<your query>)

replace <your query> with the same query up there, keeping only the fields you need for getting the "GallonsPumped" field

thanks for the help
but im still having trouble getting the results;
can you explain this a little more?
I'm trying to select a SUM() form a subquery but I keep getting:
Incorrect syntax near the keyword 'SELECT'.

I tried enclosing the whole query in parenthese, givingit an alias but it still doesnt work.
Can you explain?
which fields would I need in addition to the SUM() outside of my subquery?
thanks
john

disregard that last question;
I got the sum working;
But, it would not would unless I gave the subquery an alias;
Even though the alias was never referenced, it would not work.

attached is my syntax  that i used;
now i just have to write it dynamically;
thanks for your help.
