Hello,
I just downloaded this great program for a try out.

But I have a question, can I calculate an average of the inserted values in one row?

I have an Table with the fields ID, Date, Weight1, Weight2.....Weight30, AverageWeight.

It is not all of the Weight fields that has a value all the time, only sometimes that alla weight fields is filled.

Can you make it som that it feel that maybe just 3 of the weight fields has an value and then make on average to the field AvergaeWeight?
Hope you could help me!

Here is what you can do to calculate column averages. You need to modify Sub LoopRs in ..._list.asp for this purpose. See my changes in bold.

' display table with results

sub loopRs(rsData,nPageSize)
Total1=0

Total2=0

' Pagination:

dim iShadeTheDetail

dim iNumberOfRows

iNumberOfRows = 0

if isObject(rsData) then

  ' Pagination: UNTIL iNumberOfRows>=maxrecs

  DO  UNTIL rsData.eof OR iNumberOfRows>=nPageSize
  Total1 = Total1 + rsData("Field1")

  Total2 = Total2 + rsData("Field2")
...
  Loop

 

 



Total1 = Total1/iNumberOfRows

Total2 = Total2/iNumberOfRows

response.write "<tr class=blackshade><td class=blackshade>" & Total1 & "</td><td>" & Total2 & "</td></tr>"
end if

end sub


I hope this helps.

Hi again.
That was not realy wath I was after.
This code is calculating just as you say, the average in a column.

But wath I am after, is the ability to calculate the average of a couple of inserted weigths in the same row, to a field named AverageWeight.

Is this possibly, or Is it just possibly to calculate in columns?
