Douglas Crockford always says 'eval is evil'. JSLint will scream at you
so I would assume you didn't pass it by JSLint or didn't fix all its
diagnostics. Please do, it really spares you lots of trouble. Avoid
such constructs, there is hardly any that cannot be expressed some other
way, like:

eval("rec." + oReg[0].childNodes[i].nodeName + "='" +
oReg[0].childNodes[i].textContent + "'");

rec[oReg[0].childNodes[i].nodeName] = oReg[0].childNodes[i].textContent;

I can't say right away what's wrong with your code. I can only suggest
you use more intermediate variables to hold references that you will use
time and time again, like:

myDataTable.getSelectedRows()[0]

or

oReg[0].childNodes

And then, there is nothing more than single-stepping through that
segment of code checking those intermediate values to see if they make
sense, which they look Ok, but there is obviously something missing.
