Thanks for seconding the advice Lucy gave me. One of the main reasons I joined WebmasterWorld is because of "the advice" I've found on the net.
As a non-trained person I read books and search the net in order to learn the technology to be able to build the applications I want. But the amount of times I've tried something only to find for instance it was incorrect advice or browser compatibility was not taken into consideration or something else or something else has made a complex task a lot harder.
When I read you shouldn't even use floats I couldn't believe it, due to my lack of experience it made me think everything that I'd done to date was wrong, you can imagine what my first thoughts were.
So thank you both for the advice and enabling me to move forward instead of spending my time analysing information that makes no sense.
Once again onward and upward as they say :-)
