How to sum fields from not every row?
Hi, I have a report like on the picture below:
But I don't have any idea how to do such summing(like in this example).
I think that it's rather simple to understand, but if not:
I have to sum up every day.
There are two sums each day. One of them is the time, when employee was out the company and this time isn't included in work time(out duty). The second sum is the time, when employee was out the company and this time is included in work time(in duty).
And report sum, where I sum all those sums.
Any idea how can I achieve this?
But please, don't tell me: "Use code", just give me at least a clue![>](style_emoticons/<#EMO_DIR#>/smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />)
