Compare 2 different inputs

Hi all

I need some help, I like to setup a flow with 2 input nodes. node1 is a node with a value range between 0-100 and the other input node2 has a range between 0-5000. I like to configure the flow like: If the input from node 1 is > 80 the output is 0 no matter whats the input of node 2. If node 1<80 the output is equale to the value of node 2. I guess this is no rocket science but I'm quite new in node red and still have to learn a lot. I searched for a similar flow on the forum and the rest of the www but no succes . Can someone please help me with these? thanks in advance!

Umm did you perhaps not export the whole flow, or is this as far as you've got?

Here is a possible layout. have a go , if you have trouble ask specific questions

Darn it, too slow off the mark!
ps this flow has a "deliberate" error due to not reading the spec :smiling_face:

Hi guys, thank you verry much, based your flows I made something that works :smiley: I learnd a lot with this about the join and switch node. Thanks!
