Using the __V function in an HTTP sampler
I'm trying to accomplish something relatively basic, and getting stuck. I want to use the __V() function in order to get the value of a variable, whose name I have to generate from another varible. (I've seen this referred to as a "nested variable".)
I have an HTTP Sampler inside of a Loop controller, and I want to send the evaluated variable's value as one of the request params. In the section titled "Send Parameters With the Request", I add a parameter with name foo, and value of ${__V(gameId_${C})}, where C is the name of a counter variable. What I want to happen is that in the first iteration, the param foo gets the value of the evaluation of variable ${gameId_1}, then in the next iteration around the loop it would use the evaluation of ${gameId_2} and so forth.
When I look at the HTTP Sampler request, what I see is foo=${__V(gameId_${C})}. This implies that the function is not running at all. Perhaps I am confused about where to put function calls, but the reference says they can go just about anywhere in the test. I also tried setting a different parameter's value to another function, ${__time(YMD)}, just to see if it was something particular to the variables I was trying to use. This also resulted in the literal ${__time(YMD)} being included in the request, rather than the function's result.
If anyone can help me out, I would appreciate it.

Somehow I managed to make it work. I don't know what changed exactly, I was experimenting around a lot, and then it started working. It was quite frustrating but I gave up trying to understand it.
Is there a good place to post examples of how things can be done? I now have a working example of something that I've seen a lot of people ask questions about, and if I had been able to find a working example of it, it would have saved me a lot of time.

Re: Using the __V function in an HTTP sampler

The fact that ${__time(YMD)} does not work suggests there is a
different problem.
Which version of JMeter are you using?
FOO ${__time(YMD)}
works fine for me as a parameter in both the HTTP Samplers

I think you should be using something like this -
${__evalVar(gameId_${C })}

Maybe have a look at the For Each Controller instead of the loop
controller;
it's more suited to looping over variables in the format that your
variables
are in (var_n)
If that doesn't work for you, you can try something like this (I use
this and
it works);
${__BeanShell(vars.get("sns.testdata." + vars.get("current.sns") +
".user"))}
which takes the value of "current.sns" e.g. 'BB' and when resolved, the
value
for the variable 'sns.testdata.BB.user' is returned successful
