New to Retool --> How to connect a text box to a google sheet value

I have a large data set, that I will be going through 1 record at a time, as the user goes through the data they will up updating and adding values to the current record they are working on. It will be a conditional workflow that I will have the user process. I have a connected Google Sheet, however I am looking to create a record selector (think classic Form in an MS Access world) maybe even record selector to navigate. I have added a text box but I don't know how to link it to the cell in my selected record
