SQL Query Totals - sql

Question

I'm trying to write a query that calculates the average profit per employee for several projects.
I have a table that has employee names, what project they are working on, and how much profit they bring to their specific project each day.
My first query gives 3 fields - The project name, the sum of all the profits the employees bring to the project, and the number of employees in the project.
My second query I am trying to display 2 fields - the project name and the average profit per employee that each project makes
SELECT SAYSquery.ProjectName, SUM(SAYSquery.Profit) AS SumOfProfit, Count(SAYSquery.[EmpFirstName]) AS NumberOfEmps
FROM SAYSquery
WHERE profit > 0
GROUP BY SAYSquery.ProjectName;
SELECT SAYSqueryNIPE.[ProjectName], SAYSqueryNIPE.[SumOfProfit]/[NumberOfEmps] AS total
FROM SAYSqueryNIPE
GROUP BY SAYSqueryNIPE.[ProjectName], SAYSqueryNIPE.[SumOfProfit]/[NumberOfEmps];
Unfortunately, my second query is giving me the same average profit for every project and I'm not sure why. Any help would be much appreciated.
EDIT:
Query 1 reads:
**Employee Name | Sell Rate | Renumeration | Profit (Sell-Renumeration) | Project Name**
Query 2 reads:
**PROJECT NAME | SumofProfit | NumberofEmployees**
Project X | $1500 | 3 employees
Query 3 reads:
**PROJECT NAME | TOTAL**
Project X | $500 (Average profit per employee)

The problem is in your first query where you count the number of employees. As written in the question, you are returning a count of rows, not employees who worked on the project. You need to use count distinct. I'd also recommend not counting on EmpFirstName. If you have more than one employee with the same first name, the query won't give you correct results. It would be better to use a unique employee identifier instead of their first name.
SELECT SAYSquery.ProjectName, SUM(SAYSquery.Profit) AS SumOfProfit,
Count(distinct SAYSquery.[EmpFirstName]) AS NumberOfEmps
FROM SAYSquery
WHERE profit > 0
GROUP BY SAYSquery.ProjectName
You could wrap the whole thing up into a single query instead of two or three, as described in your question.
SELECT SAYSquery.ProjectName, SUM(SAYSquery.Profit)/Count(distinct SAYSquery.[EmpFirstName]) AS AvgProfitPerEmployee
FROM SAYSquery
WHERE profit > 0
GROUP BY SAYSquery.ProjectName
