Date Relationships

I am making a database to track telemarketers orders and calls

Here is my problem

In Table 1 I have...
sales #/order amount/order volume/date

In Table 2 I have...
sales #/call length/# of calls/date

I would like my query to output
sales #/order amount(sum)/order volume(sum)/call length(sum)/# of calls(sum)/date(by day)

Seems simple enough... but I can't seem to make this work
