I have 2 function nodes which gives output as -  
f1 node output : msg.payload.number - 123  
f2 node output : msg.payload.number - 456  
if f1==f2 then popup=employeeid.  
This should show a popup with employeeid in worldmap  
Could anyone please help how I can achieve this

Which are you struggling with comparing the two numbers or generating the world map entry?

Also show us your flow - I suspect the two values are in separate messages but I cannot tell from your description.

Here is my flow :  
[https://docs.google.com/document/d/1i5PCGMtCn08LK3MErH-CczySyK42Pllj2d3G3ersmWs/edit?usp=sharing](https://docs.google.com/document/d/1i5PCGMtCn08LK3MErH-CczySyK42Pllj2d3G3ersmWs/edit?usp=sharing)

So I want to compare the output of text input node and the output of function node before worldmap node.  
function node output : msg.payload.delivery\_id --\> received from mqtt  
text input node output : msg.payload (which is also a delivery id) --\> manually entered  
I want to compare these 2 and if they are equal I want to add a popup in worldmap..
