Hello All, I am using the below code in a function node. When it goes in it is - msg.payload.col6. When it comes out it seems to be stripped of the name and it's just payload. I'm putting 2 functions nodes and a change node into a join node and trying to do a calculation with the three outputs in a…

If all the data is in the same row you don’t need to create three paths and eventually do a join. You could do the calculation in just one function node. let l = msg.payload.col6; node.warn("col6="+l); let t = msg.payload.col10; node.warn("col10="+t); let h = msg.payload.col11; node.warn("col11="…

[image] btbr: msg.payload=LSVP; This code wipes out the content of what was in msg.payload. You might want to use msg.payload.lsvp = LSVP;

Ahh I was going to tell you that you needed to fix the flow but I see you have removed it. Did you solve your issue? P.S. In order to make code readable and usable it is necessary to surround your code with three backticks (also known as a left quote or backquote ```) ``` code goes here ``` …

Thank you very much for your reply. I haven't yet got a solution. I'll do the code again. Thanks [ { "id": "f689f3fda0f0c8b7", "type": "tab", "label": "Flow 2", "disabled": false, "info": "", "env": [] }, { "id": "9d3e060be4525873"…

can you provide a small sample of the data, say 10 rows? also add seperate debug node (set to display the complete msg object) to the output of each of the function nodes 'LSVP', 'SVP' and 'x 100' and look at the parts section of each output. What do you see?

Morning, I've put the last ten entries in the code below. The first node reads the entry when its written into the local cvs file. I'm super new to this so probably made a total pigs ear of the way I did it. [Screen Shot 2022-05-26 at 10.08.07] 2022/05/26 00:06:19,1,0.058,-0.087,2,21.3957,20.80…

Ok, you did not set the debug nodes to display the 'complete msg object' [complete_msg_object] It looks like you are trying to process the data of a couple of the columns in each row. If that correct, please explain why you are manually splitting and trying to join the data. What is the final out…

Just got back. I'm splitting the data as I need to do different calculations on different bits and thought that the best way? It's joined again to do a calculation of the results of the previous. This isn't all of the flow. I only put in the bit that doesn't work to avoid confusion. It seems thoug…

Sorry I have only been doing this for some weeks now and muddling my way through it.

Thank you very much. I will watch the videos later. Cheers for that. I'm sure it will help me. It will definitely be easier not to split everything! The code didn't seem to work. I put it in a function node after the cvs node and this was the result - [Screen Shot 2022-05-27 at 18.27.51]

Did you add a debug node to the output of the function node? The ‘node.warn’ statements are there so you can see the values of those variables in the function node. You can comment then or remove them from the code.
