Thanks Dong.
In our case, Personas (version 3) is working with both the press and enter value when using the script button. However, we have determined that other simple pieces of code, such as storing a value in a variable, are not. So we are downgrading to Personas 2 at the moment. We are on SP8, Kernel 742, and the Notes in this checklist helped, but still a lot of functionality is missing.
I appreciate your response nonetheless, and hope you and others have better luck.
Regards,
Francisco
