Calculating cumulative percentage

[Rlabi]

from monthly percentage movements as per
Excel spreadsheet.

It seems simple in Excel but I cannot get the same result in Access.

Column a is the month
Column B the percentage movement in the month and I would like to produce column C in Access

Yo man,

You can use DSUM to get a cume tote. CHeck the form. Go to the end record and add a new one and watch the cume tote change.
