Hey @limited-barista-33480 yeah your requests look good. Let's focus on your Add Button HTML next:
I can see that your click() button has an invisible element icon shown in the Cypress running (left side) history. So we need to check if the button is in the correct state when you are clicking on it:
Steps with Cypress browser:
* Start running your Cypress test with Dev Tools -> Elements open
* Put cy.pause() in your code just before your code clicks the Add button
* then gather this info please:
1 - inspect element of your Add button and share that screenshot here of the html code?
2 - share your test code here too?
3 - manually click on the Add button in the Cypress browser, does the pop-up window display?
