Hello everyone. I've used Dynamic Drive for ages, but this is my first venture into the forums!
I maintain a website for a Hospice charity ( http://www.willowwood.info). It's not at the cutting edge of web design (built at zero cost apart from my time), but it gets the message across.
They run a weekly lottery, and would like to post the winning numbers themselves every week. Problem is, they don't have anyone with experience of updating HTML and uploading it. So, I was pondering on how I could give them this facility?
My plan was to create a hidden or password-protected form page, where they could just type in the numbers. This would update a winning numbers "database" (probably an XML file), which could be sucked in to another (read only) HTML page, where the winning numbers are displayed. I'd like to show the last 4-5 weeks' numbers on this page, and use CSS to display them as "lottery balls".
Can't be that tricky, can it? Or is there a better alternative? I'd like to create this without resorting to "proper" database software behind the scenes (MySQL etc), as support from the hosting company is a bit patchy.

If you have PHP support, you can easily read/write to a basic text file.
