Data read out

Hello, this is my first time working with Thunkable and I’m not having a great time with it. I’m only used to a bit of programming and scripting in Powershell.

I’m currently trying to read the database for my blocks. This happens when the user clicks on the login button. First, the user enters their email address, which already works. Then, the text should be searched for in my text input field (Email Text) and checked to see if this email entry already exists. If it already exists, an app notification should pop up indicating that this email already exists.

The row id value is a specific value generated internally in Thunkable. But you can also use a row number (integer) for that value. You’re trying to use an email address which won’t work.

I recommend using the Firebase sign up/sign in blocks that are built in to Thunkable but if you don’t want to use those, then you need to use the Does List Contain block with the List of Values block to see if the inputted email address matches any cells in the E-Mail column of your data source.
