First how can I easily display tabular data in this forum
I am trying to build a database to record my climbing exploits. I want to keep a running sum of pitches and lengths like in the attachment (relevant data only shown - figures in brackets = what I get)
To do the running totals I have used running sum fields as follows
Num led by me Iif([led by]="me",1,0)
This works
length Iif([led by]="me",[length],0)
This does not work, the running sum is not kept as can be seen above.
If I change the field value (length), for a constant eg 6, a running sum is kept, If I just put in length as the source (without the Iif statement) it does not work. It just puts the value and not the running sum
What is going on please? Its driving me crackers
