Background Info: I am not a developer; I am simply an end-user of the system. My technical experience with DotNetNuke is nil.

The director of my company's intranet told me he has set me up to be a content editor for our DotNetNuke-driven intranet. I am, in fact, able to edit the text of announcements and add or delete announcements or sections within a page, but I get an error message when I click on the button for uploading a file to my announcement posting. I click on "Upload New File". Then, instead of seeing a windows explorer-esque environment (like what you see when you click File and then Open in most any Windows application) in which to select the file, I receive the following error message: "Edit Access Denied  Either you are not currently logged in, or you do not have access to modify the current portal module content." I have to be logged in because I see my name in the upper-right corner of the intranet pages. And, I must have editor rights, because I am able to add/edit/delete text. My company's intranet "guru" has actually given up trying to help me with this. He just keeps telling me that my access should be working.

What is going on with this error and how can I fix things? Or, how can I communicate the solution to my IT department.

Some info I see in the HTML source code:

The HTML that corresponds to the link that I click on before the error:
<a id="_ctl0_cmdUpload" class="CommandButton" href="EditModule.aspx?tabid=713&amp;def=File Manager">Upload New File</a>

You nailed it. Thank you very much.
