Count number of occurrences of a character in a string

[#1]

Hi,

I am trying to count the number of occurrences of a character in a string. How do I achieve that using JSL?

For eg:

Number of occurrences of letter 'A' in the below strings

APPLE -> 1

PEARS -> 1

BANANA -> 2

[#2]

Below formula actually works perfect.

Length( :Name( "Col1" ) ) - Length( Substitute( :Name( "Col1" ), "A", "" ) )
