Personas 3.0 - check value in a table

Hello,

I need to check if a value (personal number) is existing in the transaction OPS6.

For that I created a new flavor with two fields and a script into this transaction.

The first field is used to define the value to check and the second one to display the result of the script.

The problem with my script is that the table is bigger as the screen and when I executed it, I have an error.

When I reduce my windows, I have the same error but the "rowIndex" is different.

Here bellow I attached my script.

Does anyone have an idea to help me ?

Thanks

Dominique
