access (sql) group by query and join
===

I have two tables of data,
1. Project (ID, NAME, price),
2. Expenses (ID, NAME, price, PROJECT_ID,),
 I want to find all the projects with a summary of project expenses
I tried this query , but I could not get all the projects, only what he has expenses

    SELECT     PROJECT.p_id, SUM(EXDE.EXD_AMOUNT) AS T
    FROM         PROJECT INNER JOIN
    EXDE ON PROJECT.p_id = EXDE.P_NO
    GROUP BY  PROJECT.p_id

I would appreciate very much any answer will help me reach a solution
