modulus

getnaren

Hi,

I am trying to put the items in 2 columns based on odd even count..but its taking the first item and displaying in 2 columns(its repeating the same item in both).

and also I want to get empty cell if there is only one item (i.e right column cell should be empty)


here is the code I am using....can anyone help me/

How I've done it in the past is to iterate through the items in a foreach iw_perl block.

I have a non-zero based counter which I increment++
I also get the number of replicants up front.

my $intItems = iwpt_dcr_list('dcr.Item.Image');
my $intItemCtr = 0;

I start by writing out the content of the cell then check the details of the current iteration. At this point you should be able to get the modulus and either write out another cell or a new row.
