There you have the first problem. It doesnt tell me what the language is. If I knew it was php I could make a start.
And then it doesn't say what to do with the code examples it provides.
POSTing for me means printing it out, and putting it in a red box, perhaps a stamp?
It makes a broad assumption that I know what I am doing. At my age, new skills have to pay back quickly.
No time to buy green bananas!

I got in touch with the API people and started to look at that. Unfortunatley the guides are no doubt correct, but totally useless. So I am no further forward. Very frustrating.

PHP not my game. I found a bit of wordpress app to insert the code, but nothing is happening
What am I missing? Any clues appreciated

thanks for the update
time to ponder!!

A clue. It is not in Wales!

Thank you for explaining this. It is very useful.
I have found and set up some bus records for my area in Cheshire and am now experimenting with display on our web pages.
I see that in your display you have stripped out the graphics and just showing text. Is there a simple way to do this?
I started with iframes in wordpress. Any thoughts appreciated.
