I'm totally lost now... - I found that I've put an absolute path where it didn't belong - I fixed that, so I'm getting messages. But now I'm not getting the thankyou page - though I didn't change anything on that part!
Maybe I just need a drink.
OK, it was all my fault (stupid!) - I forgot that I =actually overtyped the thankyoupage filed with redirect for other purposes, but after a while of trying to figure it out all the little letters in the script started looking like ants to me!
Anyway, thanks, guys.
It's working fine now.
