I'm playing as a Paladin, so I get a wizard cantrip.  I want to take Fire bolt, but the option doesn't show up in the character creation pages.  After leveling up there is now a cantrips spot when I view my character, but it auto selected 'mold earth' for some reason and I still don't have anywhere that I can see to change it on the creation/update pages.

If anyone knows where/how to fix this and select the correct cantrip for my character that would be greatly appreciated.

As far as I know Paladin's don't get cantrips. Did you take the Magic Initiate feat? In that case you can switch your spells under the "Ability Score Improvement"-section (Under Class Features). Depending on your level, you might have more than one of these.

EDIT: Or are you playing as a race that get's a cantrip? Like the High Elf? In this case you can change your cantrip under your Race-Tab.

It was indeed the High Elf.  Thank you so much for helping me with this. ;) Now I can properly burn away the evil and unrighteous that plague our land.

This is totally unrelated and why are you asking random internet strangers? The answer is the spell darkvision, magic items, or dying and creating a character with darkvision. In ToA, the final option is easiest.

ok thanks but I just bought a magic item
