Hey!
I'm working on a site where ppl can enter certain data for the machines the own.
The problem is that all data from the extra fileds are collected in a single database entry, thereby making it hard (impossible?) to use this data for displaying for instance charts or other stats.

Any suggestions on how to do this?

Start by learning the syntax of the default way to do it in this blog post
getk2.org/blog/1068-k2-v262-now-available

Next, create your own array, and use the data from it to popluate things as you wish

Thank you for the link
