Remove validation for negative price

Hello,

I've seen a similar post to this, but the solution still wasn't quite what I'm needing. I am using Gravity Forms for a camp registration payment front-end.

Some campers receive scholarships of varying amounts. A coupon system wouldn't be efficient, since there are nearly an infinite number of scholarship amounts that could be awarded. What I was hoping for is a "product" field (i.e. scholarship field) that allows a negative number. I've tried that solution, and Gravity Forms accepts the negative amount and adjusts the final total correctly. However, when the user submits to pay, the script returns an error. Is there any way whereby that field's validation routine (i.e. the scholarship field) could allow for negative values? The test page is located:

Thanks,

David, I have the same issue. I want my clients to suggest a discount as a product in the user defined pricing field. It calculates fine when negative amounts are input, but when "Submit" is clicked, an error message pops up because only positive numbers are allowed. I am not good at CSS, but perhaps there is a CSS that will allow for negative numbers in the product field. Is there a solution that can be recommended?
