how will i compute the amount by using asp?

[rekcip]

Im currently doing a simple application using html and asp. I would like an application that displays basic services. The application should be designed with checkboxes to select various services such as vaccination, dentistry, laboratory work, heartworm preventive and so on. As each services selected the charges for the services should display. After all selections have been made the charges should be added together to arrive at total amount. For example if you check the value of vaccination and its amount is 300.00 and if you check the value of dentistry ant its amount is 400.00 and the laboratory work is 500.00.. what is the amount? how will i compute it by using asp?

Heya, rekcip. Welcome to TSDN!

I'm going to go ahead and move this thread to the ASP forum, where our resident Experts will be better able to help you out.

After the user makes their selections and hits submit, you check to see if the form has been submitted, and then you check to see which checkboxes have been selected, and keep a tally of the total amount.

If Request.Form <> Empty Then ' if the form has been submitted and contains information
   iTally = 0 ' Inialize a variable with a value of zero, so we can add to it.
   If Request.Form("item1") = "on" Then ' if the checkbox "item1" has been checked by the user
      iTally = iTally + 300
      isCharge = true ' set a variable to see whether anything has been selected
   End If
   If Request.Form("item2") = "on" Then ' if the checkbox "item2" has been checked by the user
      iTally = iTally + 400
      isCharge = true
   End If
   'if items are being selected of monetary value, we need to add the laboratory charge to it, if they're not purchasing anything the iTally will return 0 and I'm *assuming* you don't want to add the laboratory charge in that case
   If CBool(isCharge) = True Then
      iTally = iTally + 500
   End If
   Response.Write "Your total charge is : " & FormatCurrency(iTally,2)
End If
 

Note that checkboxes return a value of "on" when they are checked, and DO NOT return any value when they are not checked.

Hope this helps.

Sincerely,
Mark
