Roll20 SRD5 character sheet, spell casting error

I have an issue where I click a spell, and it'll work. Any subsequent casts.. hits this error: Here's the spell in the sheet: The error happens whether I use the Attacks section of the character sheet, or the Spells page. Although on the Attacks page, if I add crit dice.. even to spells that can't crit (aka Fireball) it will atleast make the error not happen.

Two things. Does it persist if you change the output from attack to spellcard and then back to attack? Do you have the global damage modifier enabled but set to an empty value?

1. Yes. It persists if swapped to Spellcard then back. 2. I see a global magic attack modifier.. but no global damage modifier. it's currently "0" Update: Found a checkbox called "Display global damage modifier" and it is unchecked. Checked it, refreshed the page, and found the field you meant. That field is disabled and blank.

Here is that entire "Config" page:&nbsp;<a href="https://screenpresso.com/=75tTe" rel="nofollow">https://screenpresso.com/=75tTe</a>

UPDATE: I have found another way of causing it to replicate, fix, then switch back and replicate. If you look at the screenshot of Earth Tremor, The Spell Attack field has 3 choices: None, Melee, Ranged. If set to None.. it causes the error. If set to Melee or Ranged, it works. Even though its neither ranged nor melee spell.. its a self centered AoE. UPDATE #2: Eeesh, this seems to have triggers everwhere. If I turn off "auto roll damage".. then Melee or ranged work. But If I have auto roll damage and crit turned on.. then none of the above work and it always errors.

Ok, so I think that this still has to deal with either of the global attack or global damage modifier. You said that these values were disabled and blank. Can you just put a 0 in these fields and see if that fixes the issue? Also, I noticed that in your screenshot you don't have the Saving throw set. I don't know for certain, but a spell set to attack may require that the spell either be a melee/ranged spell attack OR have the saving throw set. If you set the saving throw of the spell to DEX, as specified in the description of the spell, do you still get an error?

The Attack and Damage modifier fields were blank and disabled. I enabled them, and then set them to 0. No change. Disabled them back. (screenshot shows them unchecked). I re-added firebolt to my spellbook without removing the old one to show the issue. I'm not manually adding these things. DragDrop from Compendium. We're not running any custom APIs or anything. Just..&nbsp;roll20 purchased adventure and the 5e sheet. No custom classes, no special scripts. And this bug appears straight out vanilla. <a href="https://screenpresso.com/=1OgCb" rel="nofollow">https://screenpresso.com/=1OgCb</a> Changing output from Attack to Spellcard only effected the one in the attack list that was already correct. We're about to play a session right now so I'll play with my proficiency to or spell modifier to recreate the issue, then try changing the output.
