Hi there,

I need a popup window for adjusting two numerical values by the user.

As I saw it is possible to send html-code to the notification node .... So I sent html-conde for two sliders with the given steps .... That is working fine so far.

Now there are two questions:  
-1- how to set the startup-value for the sliders (I could use a function to insert the values given by a payload / global context with string operations into the given html-code, but I think that's not the way!?)  
-2- how do I get the values as output-results from the notificaion node?

There might be a description allready online but I haven't found it, so I would be glad if someone can help me.

Regards  
Joe
