Hi,
I am using your code on my site but I have different column names...
I changed these thinking I could find a replace the names in the records.php but when i go to the records.php my value names do not echo the data... why is this? I cannot get my head road why the values do not work...
I need to add another 10 columns to the records.php so what would I need to amend on the records sheet for this to work?
You help would be much appreciated.
Regards
Benny
