Step by Step setup 2 "create issue screens" based on issue type

Question

So my end goal is to have the fields that are shown on the create issue screen change depending on the type of the issue selected. I thought I knew how to do this, but no matter what I try I can't seem to get it figured out. I am going to use a very simple example, and hoping someone can walk me through step by step how to make what I desire happen.

Given I have 1 Software Project lets give it the key "PS"

I want PS to have 2 issues types we will call those Bug and Enhancement

Lets say the project has 3 fields in total: Summary, Fix version, and DueDate

When creating a ticket and selecting type "Bug" I want the screen to show "Description" and "Fix Version" only

When creating a ticket and selecting type "Enhancement" i want the screen to show "Description" and "Due Date" only

Assuming I have a brand new blank software project, what are the step-by-step instructions I must follow to make the above reality?

I can get a screen configured and showing on create issue, but my problem is when I switch issue types it still shows the same fields, and I am not sure where I went wrong, which is why I am hoping to get a step-by-step guide using the parameters above as an easy example. Hopefully, I can read that and figure out where I am going wrong.

I finally figured it out. here is the mapping:

You have 1 Issuetype Scheme that contains the 2 issue types there in

You have 2 Screens 1 for each issue type

you have 2 Screen Schemes 1 for each issue type

you make only Issue Type Screen Scheme that contains both issue types

You then go to the project and associate the Issue Type Screen Scheme you made to the project and thats that.

Another thing I am wondering is what the mapping looks like when trying to tie a screen to an issue type.

Given these entities:
Screen
Screen Scheme
Issue type Screen Scheme
and the issue type itself

so with 2 issues types does that mean:
2 Screens
2 Screen Schemes
2 Issue Type Screen Schemes

indicating that you always have to have a 1 to 1 mapping, or at some point in that chain of schemes can you do a 1 to many maybe like

2 Screens
1 Screen Scheme
1 Issue type screen scheme?
