Hi,

I have 18 questions for a quiz.

Once one question is answered the second question is displayed

when you answer the second question third question is displayed
i want to show the progress bar at the bottom which shows them how many questions they answered

so the progress bar will be from 0 to 100% completed

i will have a gif which will expand every time a question is answered

So when a user answers question one

i store one in this variable noofanswers

But when i display the gif image it shows me one instead of the image

Code:

<%
 For int_Counter = 1 TO noofanswers

  Response.Write("<script language=""JavaScript"">Progress.innerHTML='<img src=finalprogress.gif height=20 width=" & int_Counter * 2 & ">';</script>")
  Response.Flush
 Next
%>

can someone tell me what i am doing wrong

Not sure, but first I would handle this a different way.

Retrieve the total number of questions and the total number the user answered.

Take the number answered and divide it by the number of questions.

Then place that percentage as the width of the progress bar.

So if a user has 10 questions but has only answered 4, the calculation would be 4/10 or 40%.

tried it like this

Code:

totalquestions="18"
widthofimage=noofanswers/totalquestions

<img src="images/finalprogress.gif" height="20" width="<%=widthofimage%>"/>

doesnt work just shows the %

Are you sure noofanswers has a value?

Also, assign actual numbers to your variables, not strings:

Code:

totalquestions="18"

should be:

Code:

totalquestions = 18

i even tried it like this

widthofimage=noofanswers/totalquestions*100

thanks for your reply.
here is the new code

Code:

totalquestions=18
Response.write "Total Questions:-" & totalquestions& "<br/>"
Response.write "Answered Questions:-" & noofanswers& "<br/>"

widthofimage=noofanswers/totalquestions*100
widthofimage=Round(widthofimage,2)

<img src="images/finalprogress.gif" height="20" width="<%=widthofimage%>"/>

Same thing the outout is 5.56 after a user answered question 1

What does this output?

Code:

totalquestions =18
Response.write "Total Questions:-" & totalquestions& "<br/>"
Response.write "Answered Questions:-" & noofanswers& "<br/>"
 
widthOfImage = (noOfAnswers/totalQuestions)

<img src="images/finalprogress.gif" height="20" width="<% =FormatPercent(widthOfImage,0) %>"/>

todd

jmurrayhead · #9 June 6th, 2008, 01:23 PM

Which way is it huge? width or height? You should set the height using 20px not just 20.

todd2006 · #10 June 6th, 2008, 01:28 PM

Buddy,
