Well, its good to see you come over from castro-land. Welcome. The only problem with coming here and asking questions is that unlike in castro land we wont make stuff up. So for instance your question has no meaningful content by which we can determine what the problem you are having is, let alone what the solution should be.

Basically you are going to need to provide us a with the relevant part of your code that writes the data out (dont post your whole script please) and the part of the script that reads it in. Also a small snippet of (possibly censored/munged) your data would be useful. Please use CODE tags around the code that you post. (A helpful little summary of usable tags should be visible below the message post form.)

Without giving us some basic information you arent going to get much better than a sarcastic answer: probably something like "Hmm, maybe its cause you havent changed the batteries in your goldfish?"

The people here at the monastery are a very helpful bunch so if you give some good information to go on and good reason to beleive that they are helping and not doing then you'll get a good answer in a jiffy I promise.

BTW there are a couple of site documents you probably should read, but start with this one:How (Not) To Ask A Question
