Eliminating NULLs for SUM(current-group)

Question

I face the following problem:
I have some NULL values in my data which I elimnated by a <?xdofx:decode(FIELD,'',0,FIELD)?>
add. I have defined a summary field with <?sum (current-group()/FIELD)?> that results in "NaN" because of the NULLs.
But decode doesn't work in the sum(c... ) !?
Any help is appreciated.

Hi,
I didn't know about the to_number, that's useful to know.
It get's a little ugly in your template but you can work around have the sum before the for-each. The answer is to have a for-each purely to create the sum. I've had to do it for a couple of templates.
I usually put the code in a template to make it easier to read and the not put too much code in to a cell in a table. Try the following:
<?template:t_sumdata?>
<?for-each:xxx?>
<?if:ELEMENT!=''?>
add to variable
<?end if?>
<?end for-each?>
<?end template?>
The above code can go anywhere in your template, I normally put them at the end. To reference this just put
<?call:t_sumdata?><?get variable value?>
where you want the total to appear.
Thanks
