How to set a counter like last page, so I can call its LAST value?

I read here on how to extract the value of a counter.

So for my generic sols_preamble.tex I want to for example, to be able to do something like printing

foreach n in {1,...,theqnumber}{ n, }

What I am doing is to give an indication just like the lastpage thing. I want to say for exmaple, there are 8 questions in the file, you can go to Q1,2,3,4,5,6,7,8. on everypage of that file.
At the momemt, I am getting

you can go to Q1,2,3   on pages 3,4,5 of that file
you can go to Q1,2,3,4 on pages 6,7,8,9 of that file
... ... 
... ...
you can go to Q1,2,3,4,5,6,7,8 on pages 10 of that file

if there are only 10 pages and 8 quesitons.

Basically, what I need is it call the last value of my counter qnumber.
How could I archieve that?

After a bit of study at here.
I think I ran into the exact problme as discussed in the comments by Schweinebacke.

Thanks.
