D&D 5E character sheet

It saves all my stats, but for some reason won't show/save my weapons.
I enter "Short Sword" and 1d6 for the attack, but when I click to save, it disappears when the sheet comes back up

It saves for me. I note that your attack should be +4 or something, and the damage like 1d6+2. I don't know if their is a 'type' error, that it only wants a number for attack?

It does check for valid values, but should give an error when it doesn't get them. I'll look into that.

If you're only putting in the name of the weapon and 1d6 in the Attack field, ie only two fields, it won't save. You need to fill values in the Name, Attack Bonus, and Damage boxes (Notes can be left blank).

I also would like if there was a spot for vehicles/drones, which seems to be missing as if now.
Also if there could be a place to put in a # of initiative dice. Such as a [ ] D6 + [ ] .
I realise adding stuff isn't easy, and I would volunteer my help if I knew how to code... I just thought it should be noted....

what do you mean by "initiative dice"? in 5E, initiative is rolled with a d20. only thing you need is your modifier and there's already a field for that in the sheet.

if you are using some homebrewed rules that aren't RAW, a character sheet designed for a specific rule set wouldn't suffice in any case. may look into custom sheets?

also, i think vehicles can just go into the all-purpose items section.

what i think would be helpful is to add "Expertise" option to the skill instead of the binary "Prof?" checkboxx.
