process goes infinte while looping a record

I have created a process to loop through each row in a record, and for each row, I have defined a set of instructions to execute. However, I'm encountering an issue where the process enters an infinite loop.

In the "Get Script Task," I am using a simple query to retrieve data from a record. I attempted to save the query result in a multiple variable, hoping it would allow me to loop through the rows correctly, but it still results in an infinite loop.

the problem is im not able of retreiving a single value of a frild form the record , its concatenating all the values in the output  inside the variable ,and not one by one which cuases this infinte loop ,

and this what im passing for codice progetto : 

pv!ImprotPregressoPC['SC Import Pregresso PC.fields.codiceProgettoConnessione']

how can i make it retieve one by one every loop?
