hi,

i need to do message sum. for example i have message 10 i click on it and it prints first time 10. next time i click i get 10 + 10 = 20, third time and get 10 + 10 + 10 = 30 and etc. in manulal i found how to double number but i need other function.

thank you for help

correction. i have two messages 10 and -10 and i know that [f ] save value. how connect all that then i click 10 (10+10=20) and then - 10 (20 - 10 = 10)?

This should do the trick.
