I have to tell you lil_v, that you have a bad habit of posting incomplete code examples, then finding a solution for something not shown in your code. In this case, your code shows nothing about "user input", yet it was chomping user input that was the culprit. Even the node title is misleading.

I had to stare long and hard at your incomplete code example to even make an educated guess at what was wrong. From now on, if you do not post a complete working snippet that demonstrates your problem, I will likely skip over your node. Sorry.... but if you want to be lazy....so do I.
