Queries :: Sum A Value Based Off Multiple Fields

I'm trying to build a query that uses the information pulled from controls on a form called "CharacterCreation" - 2 of the controls are "Race" and "Class", and the form stores this data in a "Characters" table.The query needs to refer to the Characters table, and another table called "Modifiers".In this second table I have several numerical fields such as hp, str, etc, and I have two other fields called "Type_Modifier" and "Type" Among the Type_Modifiers are Race and Class, where their corresponding "Type" could be for instance Demon and Magician..

So the idea is that when I mark on the form (and thus creating the record in the first table) a Race of "Demon", and a class of "Magician" I want the query to refer to both of these fields, and sum the values in the second table where the "Type" is either "Demon" or "Magician" or whatever I decided to choose. I feel like I should be able to figure this out but I'm having a hard time..Here's an example of the SQL I've tried that shows nothing.

Code:
SELECT Characters.Char_Name, Sum(Modifiers.hp) AS SumOfhp
FROM Modifiers INNER JOIN Characters ON (Modifiers.Type = Characters.Class) AND (Modifiers.Type = Characters.Color2) AND (Modifiers.Type = Characters.Color1) AND (Modifiers.Type = Characters.Species) AND (Modifiers.Type = Characters.Race)
GROUP BY Characters.Char_Name, Modifiers.Type
HAVING (((Modifiers.Type)=[Characters].[Race]));

I also tried this, which I thought would work but it displays nothing as well.

Code:
SELECT Characters.Char_Name, Sum(Modifiers.hp) AS SumOfhp
FROM Modifiers INNER JOIN Characters ON (Modifiers.Type = Characters.Class) AND (Modifiers.Type = Characters.Color2) AND (Modifiers.Type = Characters.Color1) AND (Modifiers.Type = Characters.Species) AND (Modifiers.Type = Characters.Race)
GROUP BY Characters.Char_Name, [Type]=[Characters].[Race];
