This is my Custom Function and I want to edit it

Discuss:

I believe this will not work if a an earlier list element contains a later one:


e.g.,

firstgamma
gamma

and you search for 'gamma'

On reflection I suggest this change:

fpos = Position( ¶&clist&¶ ; ¶&spos&¶ ; 1 ; 1 ) + Length( spos )+1 ;

This won't work if SearchString isn't in ElementList in the first place; it will return a value anyways.

Here's a revised version:
Parameters: element_list, search_string

Let( [
s_pos = Position ( ¶&element_list&¶ ; ¶&search_string&¶ ; 1 ; 1 ) ;
f_pos = s_pos + Length ( search_string ) - 1 ;
f_list = Middle ( element_list ; 1 ; f_pos ) ;
index = ValueCount ( f_list )
] ;
If ( s_pos ;
index ;
0
)
)
