Is it possible to add a negative number to the value of a radio button.
We would like a way to offer a $10 discount for special situations.
What would be the best way to achieve this?

The Radio Button value field only allows "positive price for this value"

Thanks,

Hey Randall,

There is no way to do this using wfb itself. Hang tight someone in here may know a hack to do this. My best guess is maybe Eric will chime in and give some advise.

Are you using the paypal payment option on the form?

Yes, I'm processing the payment through PayPay using the CC embedded set-up.

I'll need to look at the paypal setup and see what can be done. It might be a while as I'm doing pc upgrades and am not on my regular machine.

I'm interested in this as well. Any ideas come up on how to create a "discount" price input checkbox value in Form Builder?
Or can you enter a negative price value manually in a field and have that deduct from the grand total of the form?

I noticed in Eric's "Running Total" example using jscript, that a negative value will work. Athough the data box is setup to require positive numbers to submit, negative values are reflected in the total before submitting. I would imagine then that there is a way for a user to input a negative value and have it reflect in the total.....

Yes that particular script does allow negative numbers. I think one way to accomplish this would be to use a regular expression for your discount input and keep it hidden. Then use a url variable to populate it from a link on your site.

I can't imagine that there's not someplace in the code -and I've been digging all through the various generated scripts- where I can make a price input value be subtracted rather than added. I'm trying to find the code where it literally adds the values so that I can put in a minus sign, a negative number or multiplier. I'm OK with either entering an amount to be discounted or using check boxes to select a predetermined amount. I realize that this code editing would have to be done each time I export the form. Anybody figured out a simple discount system yet....?

You could still do the regular expression and let user enter the value. This way they can't get a discount that the regular expression doesn't allow.
