Hello
I have written a script for concatenating columns in column "PIN_NAME"
My problem is that I don't have a constant amount of columns.
I should concatenate column from Test_name 10 until Test_name 15, but some times I have just Test_name 10 until Test_name 13 (for example)
and I received an error because the script tries to concatenate Test_Name 14, and Test_Name 15 which don't exist.
Can you assist me with this issue?

Column(dt_split,"PIN_NAME") << Formula(Char(:TEST_NAME 10 || " " ||
:TEST_NAME 11 || " " ||
:TEST_NAME 12 || " " ||
:TEST_NAME 13 || " " ||
:TEST_NAME 14 || " " ||
:TEST_NAME 15)
);
