Click activity not working for checking

Hi
I need to check the checkboxes. I have used for each activity.
to click I have used click activity.
It will click the check box but for next loop it will uncheck the checked box and then check the next check box the same scenraio repeats

@KarthikBallary use Check Activity it works well with Check boxes and RadioButton options.

Type Into Activity and send a space key can work in some cases more reliable as well
