Search Button Help

I need some help with a simple function in access.

I am trying to create an application whose purpose is to maintain a database of customer names and addresses. This is contained in a table called tblCustomers.

I have create a from whose purpose is supposed to be to search within the table by zip code and return them to the user via a report. The form is called frmZipLookup and contains a text box called 'zip' and a button called 'GetReport.' 'zip' is where the user inputs the desired zip code, 'getreport' is the button that is supposed to bring up the search results.

Now, at first I created a report called rptCustomers based on the tblCustomers, and I had the button bring up this report, however I was not sure how to limit the report to only the zip code entered on the form.

I created a query called qryZipLookup. I put tblCustomers in this query and dragged down the * field and the zip code field from the table.

I would like to use a sql statement to make this work, but so far none of the statements I have written have produced any results at all.

How can I create a button which will search within the table by the zip code field?
