How do I let people download a file from my page?

Recently I signed up with a pharmacy: affiliate progams that helps people get prescriptions cheaper..They allow for files to be put on a webpage..but how do I make this file ( a list of medications and prices) downloadable from my site?

Create a link to the file,

<a href="path/filename.extention">Medication Prices</a>

maybe it would look like

<a href="downloads/medications.doc">Medication Prices</a>

The important thing is I don't want to lose the prospective customer to the main company without getting credit for referring them.

The only way for you to get credit for the prospective customer is through your referral id. If they download something from your site that isnt in someway connected with the pharmacy, the pharmacy has no way you referred them

Well on the resource page ..they offer the list to be downloaded and offered on your website..

I guess I am not able to express what I want to know

[John]

Are you saying you want to provide a link on your website to download something from their website?

There are things like this.
And mostly they give a Code to put on your website.
And meybe they might have their own support staff, as Only they know how they manage affiliates, and track.
