As Christian Haul suggested, you can use either a prefix for your variables,
say _my or _own. Or create a JavaBean that would contain all the needed data
and have only one variable.

It's not a problem. But this should be done carefully. See generated Java
source to understand better what's happening when you apply your
logicsheets. As Vadim suggested, try to transform your XML files using Xalan
directly: XML -> your logic and see if you get what you are expecting.

Maybe ESQL code is not performed? What is the output of your page?
