Problem description:
if you enter a custom amount of cycles when buying it, and you enter a ridiculously large number (e.g. 10,000,000,000,000,000,000) the page crashes
Expected behavior:
- Should not crash
- Could output a message saying “invalid amount”
Actual behavior:
- Pages crashes
- Redirects you to “we encountered a problem page”
Steps to reproduce:
type in a very large number in the box shown in the screenshot below
