ADS system analysis error

I'm trying to create a path that includes all elements of a cascade to analyze gain, noise, ip3, etc. And this is the error I am getting:

" (budget_path.ael line 431, column 24)
Parameter 1 of db_get_inst_term_number is the wrong type "int".
Expected "dbInstTerm".
"

Does anyone know what's going on? Im using ADS 2015

You also need a port ("Term" element) at the output, so that ADS can calculate the signal path.
