Hello Shelley,
I would recommend re-copying the default screen and trying again. There is no way to re-connect the links without modifying many things.
Check also your actions on buttons and on the OnScreenLoad actions. To check the action on screen load, go to your screen designer with the view open. Click Advanced... and go to Step 2. Make sure OnScreenLoad is selected. Click edit on the sub-actions to see fields involved. I believe you removed a field on the screen that is needed in this action.
As a reminder as to copy a screen, you can either double click the current screen and choose Customize to copy. You can also click Copy on the screen (Customize -> Screens) and go through the copying steps, making sure 'Replace all links on existing screen' is checked. To switch back, go to Customize -> Tabs and Edit Tab Links... for the correct tab link. Then select the screen in the appropriate dropdown and click 'Finished Editing Fields'.
Action Sequence Order^7 means that the seventh action on the button has a problem.
