How Acumulated Value in a script Logic

Question

Hello,
We facing a problem here, that we cannot acumulated value using  script Logic.
We need to calculated a account where we need the value to this account in the previous month
Like That
                            JAN        FEB       MAR       APR        MAY
ACCOUT
A                          10           40          45         45            45
B                           7            30          20         
C                           3                        -15                  
In this case we need to save the acumulated value to all months, until the end of the year, even if we dont input value in this months.
Anyone facing this problem? 
Best Regards

You can't use a date display pattern on a text field, it has to be a date field.
The only way around that is to use scripting to format the date and then put the date in a text field - I've done this using util.printd() (I think - going off the top of my head at the moment) and there's a way to do it with FormCalc too.
Patterns work well once you get the hang of them. Display is how you want the data to look. Edit is the different ways you allow the data to be entered (multiple date, phone number patterns, etc.). Validate will validate that the Display pattern has succeeded. Data is the format to export.
I haven't had a chance to look at your new file but if you use 2 date fields with patterns you would just need: dateField2.rawValue = dateField1.rawValue; with dateField2 having date.long{} as the display pattern. Come to think of it you could use Global binding and give the fields the same name and you wouldn't have to do any scripting.
Radzmar has a good explanation of using multiple edit patterns for dates (English text is part way down): http://thelivecycle.blogspot.de/2011/10/date-patterns.html
