MySql update row, remove values in cells

Hi, im new to this platform so im testing it out for moving around some data between different databases.

And im stuck on a issue that i need to remove a value from a cell in the table. I have made a scenario with update row in a table. And put in the data i wanna change on the rows. But i also wanna remove the value from a cell, so what do i put in to make the scenario to remove the data from the cells?

Can you take a camera-viewfinder-duotone screenshot of your make scenario for me, along with the relevant module configurations and share-all-duotoneshare the images here?
