Re: [Xsltforms-support] stepping through recordset type data display

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

For those interested (not really specifically an XSLTForms issue) I have 
been playing with this problem a bit further.

The following demo illustrates what I am wanting to do.

There is one final problem in the code that I've not gotten to work, its 
the line that is commented out.

Hopefully it's self explanatory

Cheers.
