Trying to do a simple calculation (quantity * price). The Quantity is a text field, the price is a label. I want to display (dynamically) the Total in a label field.

in the Quantity field client side event I have

$(Total) = $(Price) * $(Quantity).

Am I going about this in the right way?

HI, for your case, you should consider checking out our Form Demos 20 which shows client side calculations. This example should enable you to see the calculated total in a TEXT/HTML label field. -- David

Thanks. Those are good examples. Unfortunatley what I'm trying to do is multiple products with quanties, which isn't covered by the examples.

Product 1 [checkbox] Qty: [textbox]

Product 2 [checkbox] Qty: [textbox]

Product 3 [checkbox] Qty: [textbox]

Total: [label or html]

[Purchase]

Hi Erik,

Jarrod's Form over at www.betasprings.com may be similar to what you're trying to achieve (log in as host / dnnhost).  Check out his client-side event under Advanced Field Options.  You'll probably need several hidden product total field then sum them all up for the grand total which will be passed to your payment gateway.  Thanks!

Candace -

I ended up using a series of dropdownlists with the prices set for the value (1=10.00, 2= 20.00).

I have some trouble calculating the total. I have a field named "total" which is a read only text box. Upon selecting my quantity for each item, it calculates and I can see the amount appear in the textbox. I have two problems

1. I cannot get it to display in the innerHtml of a Custom HTML field like in the examples. Here is my client script for each of my dropdownlists:

$(total) = parseFloat($(QProd1)) + parseFloat($(QProd2)) + parseFloat($(QProd3)) + parseFloat($(QProd4)) + parseFloat($(QProd5)) + parseFloat($(QProd6)) + parseFloat($(QProd7)) + parseFloat($(QProd8));

GrandTotal.innerHTML = 'Your grand total comes to:  ' + formatCurrency($(total)) + '';

2. I cannot pass the total into PayPal by using $(total). Here is my PayPal parameters:

&item_name=MOFAS&currency_code=USD&amount=$(total)&no_shipping=1&first_name=$(FirstName)&last_name=$(LastName)&email=$(Email)

Why am I having problems with my total field?

 -Thanks

the javascript is in the client events for the control only. Paypal shows nothing for the amount. If I use a static amount, like amount=1.00 it shows up as a dollar.

The code you gave me doesn't work either. nothing shows up for the grand total.

Thanks
