How to define two labels inside an environment to compute the number of pages the environment spans?

I would like to count the number of pages that a certain environment (named myenv) spans.
In principle, I set two labels, one in the beginning and one in the end of the environment.
These labels should be unique for every call of the environment, which is the part that
still fails (.tex:19: Missing endcsname inserted):

newcounter{howOftenCalled}% counts how often the environment 'myenv' was called (to create unique labels)
setcounter{howOftenCalled}{0}
newenvironment{myenv}[1]{
stepcounter{howOftenCalled}% increase counter
label{startPage:ref{howOftenCalled}}% define the first label

Your code works except that you cannot retrieve the value of your counter with ref{howOftenCalled}. If you use thehowOftenCalled} instead, everything works as expected.

Note that you may have to remove the aux file if you just copy this code into your old file that caused the problem.
