Feelin' a bit guilty about monopolising the group (3 posts in 3 days) but my
question and it's solution could interest others.
Anyhow I am having great difficulty getting my head around the below code.
Basically I want to display the form and if the username textbox is then
submitted empty, I want the form redisplayed but this time textbox
background color to be red and not yellow.
The code is something I simply knocked up so I could see how I can use
stylesheet settings to highlight boxes (or anything really) which have
failed validation. I am just wondering if I have approached this from
completely the wrong angle? I used to create forms within the page itself
but specifically want to use templates now.
Be grateful if something could have a look and give me some pointers. I know
the code below is incorrect (that's the problem).
Cheers
Phil
