How to reference columns whose name begin with a number

[#1]

I am looking to use the select where function within JSL script.

However, it wont let me reference my column as it begins with a letter i.e 20GHz_time

I want to do :20GHz_time <1000 however it won't let me.

I cant reference based on what column number it is as the columns can change from data table to data table so I need a way to capture it.

What is happening is the :20 is getting highlighted in green and this error is showing;

Invalid date/time ":20" Perhaps there is a missing "," or ")".
Trying to parse arguments of function "Select Where".
Line 63 Column 27: org << Select Where ( ►:20GHz

I also tried renaming the column but this script will be used for automation and we can't manually change the data table each time

use
:Name("20GHz_time") < 1000
to reference the column
