array value

[rivet]

I am looking for a clean calc to get a string from an array, build from a value list.

I have a id then a delimiter then the string.

001Ωthis is string one

002Ωthis is string two

003Ωthis is string three

I would like a custom calc to get the string based on the choosen number.

What is holding the array? Is it all in a single text field? A repeating field? A related field?

the list comes from a value list.

Here is where I am at, I feel it could be cleaner:

custom calc: qTip (valueList ; num)

Let ( [ vlist = ValueListItems ( Get ( FileName ) ; valueList )] ;

Substitute (

GetValue(vlist ;

PatternCount (

Left (vlist ;

Position ( vlist ; num ; 1 ; 1 )

)

; "¶" ) + 1

)

; num & "Ω" ; "")

)

If you just needed it to return the string on the nth line, you could use the MiddleValues() function:

MiddleValues ( text ; n ; 1 )

If you need it to use your index, then you could make a custom function to search the text field, or just use a calc like this:

Let(

[

index = GetAsText( Right( "000" & n; 3 ));

indexPos = Position( ¶ & text; ¶ & index & "Ω"; 0; 1 );

start = Case(indexPos; indexPos + 4);

end = Case(indexPos;Position( text & ¶; ¶; start; 1 ))

];

Middle ( text ; start; end-start)

)

BTW, If you're building this into a custom function, I'd recommend sending the return delimited text result of your value list items instead of sending the name of the value list. This should help make the CF more portable.

The function call would then look more like this:

qTip ( ValueListItems ( Get ( FileName ) ; "My Value List" ) ; num)

Thanks Edner - i am trying it now
