Issue with Sum Calculation for multiple different IDs - mysql

Question

The SQL code I have is shown below. The issue I am having is with calculating the sum of the Value of each Number. Doing them separately is okay and works when the Number is specified in the code but not when the number is not specified and I want the sum calculation to work for all separate Numbers.
{ Looks to calculate the value at the point of Tax. So all values before the tax date are ignored and all unit entries that occurred after the tax date are subtracted off the total units. The tax units are also subtracted off. The total units at point of tax, for each fund, is multiplied by the price at point of tax. The values of the funds are summed giving a total value for the number. }
This is the code I have done:
SELECT DISTINCT
A.Number,
CAST(ROUND((SELECT SUM(Val)
FROM (SELECT((S.TotalUnits -
(SELECT SUM(Units)
FROM TableIH AS F WHERE F.Fund = S.Fund AND F.Number = S.Number
AND F.Date >= (SELECT MIN(Date) FROM TableIH AS D
WHERE D.Fund= F.Fund AND D.Number = F.Number AND D.Entry = 'Tax' )
)
) * T.Price
) AS Val
FROM TableIH T
INNER JOIN TableID S
ON T.Number = S.Number
WHERE S.TotalUnits > 0 AND T.Fund = S.Fund
AND T.Price = ANY (SELECT (Price)
FROM TableIH AS E WHERE E.Entry = 'Tax' AND E.Number = T.Number)
)t
)
,2)
AS DECIMAL (25,2)) AS "Value"
FROM
TableIH A
INNER JOIN TableID C
ON C.Number = A.Number
group by A.Number
Tables are:
TableIH:
Number Fund Entry Units Price Date
12 YY RE 6 0.2 2015-02-02
12 YY Tax -10 0.1 2015-01-13
13 XX RE 6 0.2 2015-02-12
13 XX Tax -20 0.05 2014-12-11
13 MM Tax -25 0.6 2014-12-10
13 MM RE 8 0.2 2013-11-02
TableID
Number Fund TotalUnits
12 YY 2000
13 XX 1500
13 MM 500
DESIRED RESULT:
Number Value
12 [ ((2000) - (6) - (-10)) * 0.1 ] = 200.4
13 [ ((1500) - (6) - (-20)) * 0.05 ] + [ ((500) - (-25)) * 0.6 ] = 390.7
BUT GETTING: - Result is summing all instead of dividing it between each number.
Number Value
12 [ (200.4 + 390.7] = 591.1
13 [ (200.4 + 390.7] = 591.1
Any help with the errors would be greatly appreciated

Good evening, The problem is in your third nested subquery, you have no group on your sum, so it's summing all units, so you'll only get one total:
SELECT SUM(Units)
FROM TableIH AS F WHERE F.Fund = S.Fund AND F.Number = S.Number
AND F.Date >= (SELECT MIN(Date) FROM TableIH AS D
WHERE D.Fund= F.Fund AND D.Number = F.Number AND D.Entry = 'Tax'
