How to display information in the title of a userform

I have a userform that collects data from the user.

I ask the user how many surveys they wish to input. For each survey i show the user form and collect data. So if the user inputs they want to collect data on 4 surveys then i create a loop where i show the userform i created "4" times. What i want to do is each time through the loop i diplay which survey they are collecting data "for". I was thinking of showing this via the title of the user form.

Not sure how to do this? any ideas?
