simple question

[yall]

hello I encountered this problem I do not know where my error comes from.
I created 2 buttons that control the same parameters of a reverb. in fact, it is simply a shortcut for the 2nd button. I did it on a few effects so as not to have to go through the hise macro.
I have this sentence which appears in red. Any ideas?

Accessing parameter reference outside the function call

I compared what I had written with other duplicate button, for me I don't see any problem since it works
