I am able to post a survey where a person is asked to select multiple responses, giving a cap to the maximum number of selections allowed. Example please choose 25 from the list of 100.

In an instance like this is it possible to have a counter showing how many selections the person has made, while they are answering the questions, for example:

You have 23 of 25 selections made

or:

You have 2 selections remaining?

Any help is greatly appreciated.

I think limesurvey can do it easily.
Assume your multiple choice question is Q1. You will need to set max answer to 25 (in advance setting). And in your question text, you can put something like "You have {count(that.Q1)} of 25 selections made"

Thank you, I'll give that a try!
