running total time period

[dadaboss92]

Hi,

My table t_activity has got:
a foreign key key_project related to the project name
a foreign key key_architect related to the architect name
date
period which is a combo list with AM and PM

In my form i write the name of the architect who work on a project, the date and if it was during the AM or PM

I would like to follow up the time spent on each project. To succeed i need a running total of the AM and PM period for each project according to the dates

Cumul progressif

Projet1 17/05/2015 6

Projet2 18/05/2015 3
Projet2 18/05/2015 5


I tried many fonction as but none work:
Expr1: DSum("[period]","t_activity","[date]='" & [date] & "'")
Expr1: DSum("[period]","t_activity Query","[date]='" & [date] & "'")
Expr1: DSum("[Countofperiod]","t_activity","[date]='" & [date] & "'")
Expr1: DSum("[Countofperiod]","t_activity Query","[date]='" & [date] & "'")
Expr1: DSum("[period]","t_activity","[date]=#"&[date]&"#")
Expr1: DSum("[period]","t_activity Query","[date]=#"&[date]&"#")
Expr1: DSum("[CountOfperiod]","t_activity","[date]=#"&[date]&"#")
Expr1: DSum("[CountOfperiod]","t_activity Query","[date]=#"&[date]&"#")


Expr1: Dcount("[CountOfperiod]","t_activity Query","[date]=#"&[date]&"#")
Expr1: Dcount("[CountOfperiod]","t_activity","[date]=#"&[date]&"#")
Expr1: Dcount("[period]","t_activity Query","[date]=#"&[date]&"#")
Expr1: Dcount("[period]","t_activity","[date]=#"&[date]&"#")
Expr1: Dcount("[Countofperiod]","t_activity Query","[date]='" & [date] & "'")
Expr1: Dcount("[Countofperiod]","t_activity","[date]='" & [date] & "'")
Expr1: Dcount("[period]","t_activity Query","[date]='" & [date] & "'")
Expr1: Dcount("[period]","t_activity","[date]='" & [date] & "'")




Expr1: DCount("[key_architect]","[t_activity]","[key_Project]=""" & [key_Project] & """ AND [Date]<=#" & Format([Date],'mm/dd/yyyy') & "#")
Expr1: DCount("[key_architect]","[t_activity]","[key_Project]=""" & [key_Project] & """ AND [Dateexec]<=#" & Format([Dateexec],'yyyy/mm/dd') & "#")
Expr1: DCount("[key_architect]","[t_activity]","[key_Project]=""" & [key_Project] & """ AND [Date]<=#" & Format([Date],'yyyy/mm/dd') & "#")

I give you some screen shots also

Thank you in advance

Running total is not easy to do in form or query. Textbox on report has a RunningSum property so is easy on report.

Do you need a running total or do you need a total count of periods for each date on each project?

SELECT Project, [date], Count(Period) AS CountPer FROM t_activity GROUP BY Project, [date];

Is the date field a date/time type, not text?

DCount("[period]","t_activity","[date]=#" & [date] & "# AND Project='" & [Project] & "'")


Date is a reserved word and should not use reserved words as names.

Thank you for your reply but it doesn't work.

It is essential for me to have the running total per date and per project in order to do a graph. I need data to make it (running total = axis y) & (date = axis y).

If there is another solution or idea, even to add or modify my table i am ok.

Thank you

"Doesn't work" means the query runs without error but doesn't provide the output you want?
