Assign multiple selection column list item with a quantity?

Question

I have created a Parent List that has a multiple selection checkbox for "Media Type". If a user chooses multiple media types, I want user to add a quantity to each media type selected. I am using SharePoint 2010. I am a novice so I am somewhat limited to SPD, InfoPath and using "simple" code of the brilliant SP developers from internet searches. Assistance is appreciated.

Out-of-the-box having such behavior is not offered by any component. You could however opt for:

1. Change the Edit form into an InfoPath and rely on few Action rules and Formatting rules you could decide to toggle visibility on the "Media-Type" to store data, see here to get started http://allcomputers.us/windows_server/infopath-with-sharepoint-2010---use-the-edit-form-on-the-list-page.aspx and here to Show/Hide fields based on conditions http://office.microsoft.com/en-us/infopath-help/hide-or-disable-a-control-based-on-values-in-a-form-HP001096364.aspx
2. Customize the EDIT Form to include some JavaScript code to show/hide (see here http://sharepointsherpa.com/2008/08/26/sharepoint-2007-hiding-fields-on-newformaspx-and-editformaspx-the-easy-way/)

In both cases, you should probably create additional columns for each quantity you need to store per record.
