Things are settling down now and whatever the technical problem was is resolving.
I determined what I was missing - and this is a newby question but one I wanted early so not to go to far and find I was missing something.
I was looking for a comment that said:
Your section marker will show a varible and will change once you place that section on a sheet.
Only then will the marker update with the information

I'm working in the default ArchiCAD template since I'm just playing with some stuff.
But anyway, I've placed a section marker. It hasn't been placed on a sheet yet.
Its ID is S-01, So we can change it to section "A" to achieve what you want.
I'm a fan of this 2 level marker, so I can show the ID on top and Sheet reference on the bottom. eg A/A1.00
The key box is the marker reference, which lets you select where the reference goes to.
Anyway the marker text, secondary text, notice how on my screen shot the layout reference is greyed out? Thats because it hasn't been placed on a sheet yet, but once I've done that, I can click into the marker reference box and decide where its linked to.
Normally once all this is done, you need to go back into the marker text and the secondary level and untick a box from memory.
