Math add to a buffer number

I have this payload that I need to add with 1, but i cant get it working.
Can someone help?

Udklip

var askno = msg.dynet[5] ;

msg.askno = askno ;

msg.askno1 = askno + 1;

return msg;

That looks fine, with the limited look at your debug it is hard to say what's occurring . Is the debug set to show the complete message output

works for me.

When you say it isn't working...... what are you getting and what are you expecting? What does a debug on the output show?

Really sorry, I my received buffer did send the wrong number, the code was correct

Thansk for your response
