Hello, I am having some trouble with getting the value of global variable being set, in functions. Below is the flow screenshot; [image] Function 4 goes: global.set("TRIGGER",msg.payload); var res = global.get('LENGTH'); var res1 = global.get('CABLE_DESCRIPTION'); var res2 = global.get('FAUL…

Right at the start of this thread, you had the code: global.set("TRIGGER",msg.payload); var res = global.get('LENGTH'); var res1 = global.get('CABLE_DESCRIPTION'); var res2 = global.get('FAULT_STRING'); var res3 = global.get('TRIGGER') if(res3===true){ msg.payload = "res"+"res1"+"res2"; } else{ ret…

[image] an93: var res = global.get('LENGTH'); var res1 = global.get('CABLE_DESCRIPTION'); var res2 = global.get('FAULT_STRING'); var res3 = global.get('TRIGGER') if(res3===true){ msg.payload = "res"+"res1"+"res2"; } You are trying to construct the msg.payload from strings, and not the v…

[image] an93: return msg[null]; What does that line do? I don't think it is valid javascript, but perhaps it is some subtle syntax that I have not met so far. I wonder whether you meant to say return null

@Paul-Reed , how do i call the global variable then, supposedly saying For Ex: global.set('LENGTH',msg.payload); return msg Is it supposed to be var res = global.get('LENGTH');

[image] an93: how do i call the global variable then, You are calling the global variables correctly, but when you are trying to create the msg.payload you are referring to the variables as strings, because you have added speech marks around the variable's names. Are res, res1 and res2 numbe…

Yes res and res1 are numbers, res 3 is string, tried changing it but no luck yet global.set('TRIGGER',msg.payload); var res = global.get('LENGTH'); var res1 = global.get('CABLE_DESCRIPTION'); var res2 = global.get('FAULT_STRING'); var res3 = global.get('TRIGGER') //var rest = msg.payload; if(…

[image] an93: var res2 = global.get('FAULT_STRING'); Is res2 a string (it's called FAULT_STRING?) if so, it's like trying to add values like; 3 + 4 + donut = ???

global.set('TRIGGER',msg.payload); var res = global.get('LENGTH'); var res1 = global.get('CABLE_DESCRIPTION'); var res2 = global.get('FAULT_STRING'); var trig = global.get('TRIGGER') if(trig===false) { msg.payload = res; } else{ return msg; } res is float which should "var" as datatype …

[image] an93: else{ return msg; } What is the msg - it's not defined. Bedtime for me :wink:

its supposed to be null if the condition does not meet Bedtime @5 on friday. LAME !!!!!!
