Error to Ramp number of users.

Hi All
I am trying to ramp 5 users out of 10, but facing some issues.

I am trying to ramp 5 users out of 10

Not what you’re doing: you’re starting 10 users at the same time, then try to ramp 5 users

rampUsers(5)
Wrong. rampUsers expects a duration, eg rampUsers(5) over(10 seconds)

Thanks.
It worked for me.
