Cannot get script working (multiple conditions)

Hi there,

I kindly ask you for some help because I'm stuck on a script for a customer.

My conditions work fine when alone, everytime I try to combine my conditions, i won't have any output when scanning (bulding the script returns no error).

Do you have an idea of what I'm doing wrong please ?

Device : MC92 CE, using TNCE v7.3.252

Thank you,

Nicolas
