Oh wow - yes, - this looks like exactly what I'm after - incorporating and and modifying behaviors, and the dynamic data section and bindings. Simulations are especially useful to me - I seem to take so much more in when I can see what's happening. I get word blindness fairly quickly when reading, always have.
Thank you so much.
The behavior I was interested in was mentioned somewhere - but I lost the post - it was to do with adding a download file behaviour - but I'd better not get into that just yet, as I'm afraid I didn't use WebAssist software to organise the upload/download bit of the page I set up. I'll be getting DF Pro eventually, - and I may have a question or two and will come back to you then, if I may.
The sims you link to will be great for now.
Many thanks.
Edit: Oh - I see, 'server behaviors' are different from just 'behaviors'. Getting it - bit by bit. Baby steps.
Later that same evening - Exciting Update: I'm ecstatic. Chapter 20 has done more for me in 10 minutes than all of my inept fumblings have produced in weeks. I can visualise now - therefore I can do. Soo much appreciated.
