[5e OGL] Noob question, sorry if it exists already

In the 5e character sheet, whenever I input an action for an npc, attacks that do damage have a "+0" that is added on after the normal rolls and modifiers. I can't figure out where this is coming from, and would love some insight. Thanks!

Before someone can help you, we need to know which of the three sheets you are using. :) OGL by Roll20 <a href="https://app.roll20.net/sheet-previews/ogl5e.png" rel="nofollow">https://app.roll20.net/sheet-previews/ogl5e.png</a> Community Contributed <a href="https://app.roll20.net/sheet-previews/dnd5e.png" rel="nofollow">https://app.roll20.net/sheet-previews/dnd5e.png</a> Shaped <a href="https://app.roll20.net/sheet-previews/dnd5eshaped2.jpg" rel="nofollow">https://app.roll20.net/sheet-previews/dnd5eshaped2.jpg</a>

Ogl. Sorry, I forgot I opened a thread haha. Thanks!

The OGL sheet uses those +0's to prevent rolls from requiring certain fields on the sheet to be filled out. If those +0's were not there some, some rolls would throw errors or fail if a user did not fill out certain fields on the sheet. For example, an NPC's damage roll typically looks like [[@{attack_damage}+0]]. If the attack_damage field on the sheet is not filled out, then that roll becomes [[+0]], which resolves. If this +0 was not there, then the roll would become [[]], which will throw an error and cause the entire damage macro to fail.

Ah, so its a restriction of the macro system, gotcha. I was confused because I thought it was pulling a value from somewhere that I had accidentally entered. It doesn't display the +0 on damage so it's not a visible issue, just wanted to be sure I was entering things correctly. Thanks!
