Default Form's calculated field not working properly

Greetings,

I have a form with 4 values that I want to sum for each detail record displayed. Something like this.

val1 val2 val3 val4 sum of these 4 values
val1 val2 val3 val4 sum of THESE 4 values
.
.

When I sum these values. I get a result BUT it appears on all records in the form... not just for the individual detail. Like this:

2 2 2 2 8
2 1 1 1 8

If this explains it enough, how can I make it so it works like this?

2 2 2 2 8
2 1 1 1 5
etc.
thank you...

Paul

Yes... It is a continuous form. My query is a stored procedure...

In the form I have an unbound field... not part of the stored procedure, that has a sum statement:
=Sum([ArcDistanceA]+[ArcDistanceB]+[ArcDistanceC]+[ArcDistanceD]).
A clue is that when I only sum ArcDistanceA it sums up all ArcDistanceA values in all 4 records, not just the one record.
I must be missing something.

Hope that helped explain it further...thank you..

This won't work in a continuous form. Try doing your calculations in the query itself by adding a column and summing the four columns in the query, and then display the summed column in your form.

Sir,

A wrinkle is this... you knew there was a wrinkle...

The 4 values will need to be updatable and the sum field will need to reflect it. In trying a stored procedure before, I could not update the 4 values. Did I mention I was fairly new to Access 2003?

thanks for your thoughts and help on this.

Does it have to be a continous form?

Tried it. It says that the field (value 1) can't be edited because it is part of an expression. Perhaps there is something I do not have set that would be intuitive to someone like you. By the way, doing the sum field your way... i.e. is a SP makes the sum calculation work for each line. That's good. I just can't update the 4 values. probably something simple...

thanks...

Put the calculation on the data entry form, not in an SP on the server. Put the calc on the Before Insert and Before Update event of the data entry form.

Me.CalcdField = Me.Field1 + Me.Field2 + Me.Field3 + Me.Field4

That sort of thing.

I must be missing something. It sums...but it sums for the current record... THEN applies that sum value to every record. I tried it continuout, single, and datasheet form.

Hmmm.
