Node MCU analog.A0 to string to CSV

So i have this problem where i try to read a temp and a Voltage of a battery and store these into a CSV file. But as you can see, i don't get the string value of the Analog input. Instead i just get the text. I've tried different parameters for the "to the value". But i still just get the text of the input i'm looking at.

As it would, as that what you are telling the change node to do.
you have to set to A/Z not msg.
