How to ignore the first argument in view contextual filters? I am having path aliases of the form

path/val1/val2/data


that are created with pathauto. I want to create a view that will be use a contextual filter and that will read only section 3 of the URL. When I set the view path to: 

path/%/%/data


then I need to specify a contextual filter for section 3 (val2) that cannot filter my data properly. 

My configuration looks like:


Filter configuration:



So I need the CELEX content filter to match section 3 of the URL. Can I entirely skip %2 and just filter based on %3? Alternatively, can I declare the second section to be a wildcard in the view path?

When I attempt to Provide default value as Bryan Jones suggested, then it seems that default value doesn't work because the context filter actually DOES match the URL section, whereas the default value is provided when the filter value is NOT in the URL

What I see after previewing the view is

Context values:


Query:
(Notice the value that I wanted to be val2)
There is a specific contextual filter called "Global: Null" that you can employ to ignore a path part and leave the query unchanged. You will have to reorder the filters so that Null is in the right position (in your case, the first, since you want to ignore the first % of the path). See the screenshot:
