Hello guys,  
I am new to Node RED and have made some simle function and dashboard to use on my boat.  
I am now trying to make the code in the picture. It is not working and I made it just for illustration only.

 ![B16DB8D8-439E-4615-8676-F9BF36E22024](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/5/7/57903ac47ec29dcebdd79d4c70051a76cb6edd2d.jpeg)

What I am trying to make is this:  
I read in the battery state of charge, if the Automatic charge current switch in the dashboard is set to TRUE, a value of X (120 in my example) is sent further.  
Then I want to reduce this value based on a temperature input.  
After the temperature reduction the value is sent to Charge current limit.  
If the value is over 20% I want no value to be sendt to the Charge current limit node.  
Instead I want to use the next line to adjust the 20-30%, 30-40% and so on.

Can someone please be so kind to show me how?  
Remember I am all green here. Please feed me with a teaspoon 🙂
