Month Over Month

Kostas Vergos

Hi,
I am very new to the access programming. I tried the month over month procedure exactly as the video describes and i get wrong results as the following table:
Y          M     Expenses        Y2        M2     BeginDate      EndDate        Previous month Expenses
2020     11     500             2020     10    1/10/2020      31/10/2020               0,00
2020     12     600             2020     11    1/11/2020      30/11/2020               500,00
2021      1     33.169,10     2020     12    1/12/2020      31/12/2020               1.100,00
2021      2     100              2021     1      1/1/2021        31/1/2021                33.169,10
2021      3     100              2021     2      1/2/2021        28/2/2021                32.964,50
2021      4      50               2021     3      1/3/2021        31/3/2021                33.057,20

Pls i need your help on this
Thank you

Can you post the exact function you are using for PreviousMonthExpenses

	Kostas Vergos OP @Reply 5 years ago
Sorry for the delay, the function is: Previous month expens: Format(Nz(DSum("[Expenses]";"[MyTable]";"[ExpenseDate]>= #" & [BeginDate] & "# AND [ExpenseDate]<=#" & [EndDate] & "#");0);"Currency")

	Kostas Vergos OP @Reply 5 years ago
Hi Kevin, Just a reminder that i have posted the function for PreviousMonthExpenses

	Scott Axton @Reply 5 years ago
You have a semi-colon ' ; ' for the NZ which should be a comma ' , '. Yours: [EndDate] & "#");0);"Currency") Should be: [EndDate] & "#"),0);"Currency") Access wont even allow the the semi-colon. Did you copy and paste the formula here or re-type it?

Scott thank you for your reply. My computer's operating system accepts semi colon for access but i chenged the settings to accept comma instead of semi colon. Still i get the same wrong results.
Also in your reply you wrote "Should be": [EndDate] & "#"),0);"Currency"). If i put a semi colon before ;"Currency" is not accepted by Access.
So, i copy-paste the formula as it is now but as i said i get the same wrong results:
Previous month expens: Format(Nz(DSum("[Expenses]","[MyTable]","[ExpenseDate]>= #" & [BeginDate] & "# AND [ExpenseDate]<=#" & [EndDate] & "#"),0),"Currency")

	Kostas Vergos OP @Reply 5 years ago
Scott, a note about the dates, in my country and in my operating system the format is as follows: dd/mm/yyyy instaed of mm/dd/yyyy as is in your region.

	Richard Rost @Reply 5 years ago
I recreated the query EXACTLY using your data. My results come out just fine. So you either typed something wrong in while building the query, OR it's a regional problem. I've only tested this with US date formats.

	Richard Rost @Reply 5 years ago

	Richard Rost @Reply 5 years ago
All of the functions that I used, DateAdd, DateSerial, Month, Year, etc. should be completely regional agnostic.

	Richard Rost @Reply 5 years ago
Let me see your raw data from the table.

	Kostas Vergos OP @Reply 5 years ago
Thank you very much, i will keep working on that.

I don't see anything that jumps out with your data. It's got to be your regional settings. See this other thread from Kevin. He had the same problem, switched to US format, and it worked fine. You've got me. I'm not an expert with anything other than US dates.

	Kostas Vergos OP @Reply 5 years ago
Hahaha, thank you very much, i ll keep trying and i ll let you know

	Kevin Robertson @Reply 5 years ago
Kostas, Formatting even one of the dates to U.S format seems to work. Previous month expens: Format(Nz(DSum("[Expenses]";"[MyTable]";"[ExpenseDate]>= #" & Format([BeginDate], "mm/dd/yyyy") & "# AND [ExpenseDate]<=#" & [EndDate] & "#");0);"Currency")

	Kostas Vergos OP @Reply 5 years ago
Richard, i used the formula Kevin wrote for me, formatting the date to U.S format: Format([BeginDate], "mm/dd/yyyy", solved the problem Thank you very much Kostas

	Richard Rost @Reply 5 years ago
Thank Kevin. Make sure to give him a LIKE (Heart). :)

	Kostas Vergos OP @Reply 5 years ago
Kevin, You are great!!!!, thank you very much for your help. Everything works fine. Kostas
