AbleCommerce Shopping Cart Software

Hi,

I am receiving an error that the max upload file size is 4 MB with AbleCommerce. I am trying to upload files from a page, which is linked to the shopping cart. So, I am trying to upload files related to an order before I checkout. I am not using FTP, just a .NET file upload tool. Is there any API that restricts file uploading to a certain size? I have these web.config settings:

<system.web>

<httpRuntime maxRequestLength="102400" executionTimeout= "3600" />

</system.web>

<system.webServer>
<security >
<requestFiltering>
<requestLimits maxAllowedContentLength="1024000000" />
</requestFiltering>
</security>

Are there any other settings I can change?

I think at one time in the past there was something we needed to do on a server level also. I just can't remember what it was. I remember finding it via Google search.
