================================================
When it is runn, the number in the loop function WONT INCREASE/CHANGE the number. What did I do wrong?

[Tech Support]

Did you start the macro with the LOOP button instead of PLAY?

[Adarkness]

I started it with the LOOP button because a message would always pop up stating that in order for the !LOOP function to work, you need to click that button.

Play(Loop) Max:200

Max must Greater than 123.
You can rewrite your code,not use "CONTENT={{!VAR1}}{{!LOOP}}"
