Hi @Analyst Kumar​ ,

Numbers have to be converted to string either by using the Number: To String Action.

Or, by using inline operations, which is what I prefer:

It isn't necessary to memorise the syntax, just add a period just before the last dollar sign and intellisense pops up.

Also, since its a field which only accepts strings, F2 won't show the number variables, so you have to write numbers by invoking intellisense(starting your variable declaration using $).

Kind Regards,
