SSRS Dynamic Running Total - reporting-services

Question

I am trying to include a cumulative total column in a matrix on a report.
This is the expression I am using at the moment:
=RunningValue(Ceiling((SUM(Fields!MINUTES.Value)/60)*4)/4,Sum,"RowGroup")
The problem is the total seems to reset on each day.
I have 3 groups on the report: Parent is Day of month, type, then sub type.
I want it so that the sub types will accumulate across the days:
So 1st june/holiday/annual = 2 - cumulative = 2
.. 2nd june/holiday/annual = 1 - cumulative = 3
rowgroup in the expression above is the 3rd level sub type group in the matrix.
Whatever I try I cannot get it to total up over the days, like i said above it seems to not carry over to the next day.
Below is a sample dataset:
+------+------------+---------+----------+---------+
| User | Date | Type | Subtype | Minutes |
+------+------------+---------+----------+---------+
| 158 | 13/02/2015 | Holiday | Annual | 90 |
| 158 | 13/02/2015 | Meeting | Training | 300 |
| 158 | 13/02/2015 | Lunch | Lunch | 60 |
| 158 | 03/06/2015 | Holiday | Annual | 120 |
| 158 | 03/06/2015 | Meeting | Meeting | 285 |
| 158 | 04/06/2015 | Holiday | Sick | 120 |
| 158 | 04/06/2015 | Holiday | Annual | 200 |
+------+------------+---------+----------+---------+
My matrix column group is the user.
The row groups are date, then type, then subtype.
I then have a total column outside the column grouping.
I'm now trying to add in to the report a cumulative total based on the type and sub-type columns, that sums up the minutes.
As an example (looking at the holiday, annual entries):
03/06/2015 - 120 minutes
13/02/2015 - 90 minutes = 210 minutes
04/06/2015 - 200 minutes = 410 minutes.

Taken from the MSDN page for RunningValue, adding a scope to your expression will have this effect.
The value for RunningValue resets to 0 for each new instance of the scope. If a group is specified, the running value is reset when the group expression changes. If a data region is specified, the running value is reset for each new instance of the data region. If a dataset is specified, the running value is not reset throughout the entire dataset.
To fix the issue, simply remove the scope:
=RunningValue(Ceiling((SUM(Fields!MINUTES.Value)/60)*4)/4,Sum)
This will have the total run across all days (As days are your top-most level). If this is incorrect could you perhaps give us an example of what the report is currently doing, and what you want it to do?
