Issue with scroll view in titanium?

I have a form which has 10 questions with rating bars. I need to display 10 questions in same page. The questions won't fit for a screen so I need to make a vertical scroll and should able to view 10 questions in same page. I tried many ways But it is not working. Please help me with vertical scroll view?

And the style code is as follows for the above view,

"#questionnaireWin": {
    layout: 'vertical',
    fullscreen: false,
    navBarHidden: true
}

"#header": {
    top: 0,
    height: "50dp",
    width: Ti.UI.FILL,
    backgroundGradient: {
        type: "linear",
        startPoint: { x: "0%", y:"0%"},
        endPoint:   { x: "0%", y:"100%"},
        colors: [
            { color: "#4F94CD", offset: 0.0 },
            { color: "#4F94CD", offset: 1.0 }
        ]
    }
}

"#title": {
    align: "center",
    color: "#fff",
    font: {
        fontSize: '21dp',
        fontWeight: 'bold'
    }
}

".questionsContainer":{
    height:Ti.UI.FILL,
    width:Ti.UI.FILL,
    layout:'vertical',
    backgroundColor:"#f39c12"
}
'.row':{
    height:'20%',
    width:'100%',
    backgroundColor:'#bdc3c7',
    layout:'vertical'
}
".question":{
    font:{
        fontSize:18,
        fontWeight:'normal'
    },
    color:"#000",
    left:10,
    height:'50%'
}
".starRating":{
    height:'50%',
    left:10
}
".processRating":{
    height:45,
    width:'90%',
    backgroundColor:'#3498db',
    color:'#fff'
}

This one was interesting. You have 10 rows, but each row is "20%" of the size of the questionsContainer. That means there is only enough space for 5 to show on the screen.

'.row':{
    // height:'20%', // <--- Change this to something else that isn't 20%
    height: "200dp",
    width:'100%',
    backgroundColor:'#bdc3c7',
    layout:'vertical'
}

Let me know if that doesn't fix it for you. I had made 4-5 other modifications before I stumbled on that one.
