Returning more than one of same acct instead of sum for both

Code not combining acct number results.
The code below returns for example:
74981995170968 1595.00 253.54 1341.46 940.40
74981995170968 1595.00 2281.86 3876.86 940.40
It should be:
74981995170968 1595.00 2535.4 1341.36 940.40
above values come from
2281.86 + 253.54 = 2535.4
2535.4 - 1595.00
When I need it to combine the information and it's not because of the CASE statement within my first INNER join where I choose to SUM rmstranamt based on if there are more than one record or not
.
Here's the query:
SELECT rm.rmsacctnum,
SUM(rf.rmstranamt) AS [Sum rmstranamt],
rf10.rmstranamt10 AS [Sum rmstranamt 10],
CASE WHEN SUM(rf.rmstranamt) > SUM(rf10.rmstranamt10) Then
CASE WHEN SUM(rf.rmstranamt) < 0 AND rf10.rmstranamt10 < 0 Then
SUM(rf.rmstranamt) + rf10.rmstranamt10
WHEN SUM(rf.rmstranamt) < 0 AND rf10.rmstranamt10 > 0 Then
SUM(rf.rmstranamt) + rf10.rmstranamt10
WHEN SUM(rf.rmstranamt) > 0 AND rf10.rmstranamt10 > 0 Then
SUM(rf.rmstranamt) - rf10.rmstranamt10
WHEN SUM(rf.rmstranamt) > 0 AND rf10.rmstranamt10 < 0 Then
SUM(rf.rmstranamt) + rf10.rmstranamt10
END
WHEN SUM(rf.rmstranamt) = 0 AND rf10.rmstranamt10 = 0 Then
0.00
WHEN SUM(rf.rmstranamt) = 0 AND rf10.rmstranamt10 <> 0 Then
SUM(rf10.rmstranamt10) + SUM(rf.rmstranamt)
WHEN SUM(rf.rmstranamt) <> 0 AND rf10.rmstranamt10 = 0 Then
SUM(rf.rmstranamt) + rf10.rmstranamt10
ELSE
CASE WHEN SUM(rf.rmstranamt) > 0 AND rf10.rmstranamt10 < 0 Then
SUM(rf.rmstranamt) + rf10.rmstranamt10
WHEN SUM(rf.rmstranamt) < 0 AND rf10.rmstranamt10 < 0 Then
rf10.rmstranamt10 + SUM(rf.rmstranamt)
WHEN SUM(rf.rmstranamt) > 0 AND rf10.rmstranamt10 > 0 Then
rf10.rmstranamt10 + SUM(rf.rmstranamt)
WHEN SUM(rf.rmstranamt) > 0 AND rf10.rmstranamt10 < 0 Then
SUM(rf10.rmstranamt10) + SUM(rf.rmstranamt)
WHEN SUM(rf.rmstranamt) < 0 AND rf10.rmstranamt10 > 0 Then
rf10.rmstranamt10 + SUM(rf.rmstranamt)
END

HAVING cb.CurrentBalance <> SUM(rf10.rmstranamt10) - SUM(rf.rmstranamt)
AND cb.CurrentBalance <> 0.00

sorry I'm getting dizzy just looking at that. However, I think the following line might be flawed:
CASE WHEN COUNT(*) > 1 THEN

Basically this will always return true whenever the rfinanl table has more than one row.

Sorry I can't be of more assistance.

finally, I got this figured out:

INNER JOIN
(
SELECT RMSFILENUM,
SUM(distinct rmstranamt) AS rmstranamt10
FROM RFINANL
WHERE RMSTRANCDE = '10'
GROUP BY RMSFILENUM
) AS rf10 ON rf10.RMSFILENUM = rm.RMSFILENUM
