Uses the Trim4() custom function.


Let(
[
allvalues = Trim4( Lower( values ) ) ;
firstvalue = Trim4( GetValue( allvalues ; 1 ) ) ;
firstcount = PatternCount( "¶" & Substitute( allvalues ; "¶" ; "¶¶" ) & "¶" ; "¶" & firstvalue & "¶" ) ;
newvalues = Trim4( Substitute( "¶" & Substitute( allvalues ; "¶" ; "¶¶" ) & "¶" ; [ "¶" & firstvalue & "¶" ; "" ] ; [ "¶¶" ; "¶" ] ) )
] ;

Case(

IsEmpty( allvalues ) ; "" ;

firstvalue & separator & firstcount & "¶" & SummariseValues( newvalues ; separator )

Hello there,
My name is Abraham. I just downloaded the above named custom function but the manage custom function in filemaker does not accept it with popup saying “too many parameter”. Do you have any idea?
Thank you very much
Abraham

Hello Abraham

When defining the custom function in your database, do it in this order:

1) Enter the function name "SummariseValues"

2) Add the "values" and "separator" parameters (type each name and click on the little green + symbol)

3) Paste the calculation expression into the body of the custom function.

If it's done in this order then it should work.

My guess is the add parameters step has been missed.

All the best,


Vaughan

A minor alteration, possibly of use: instead of a separator, a string format template is supplied, with n being replaced with the summary count. It makes appending things like " (n)" easier, but still allows for "separator n" type formatting...

// SummariseValues ( values ; suffixFormat )
Let(
[
allvalues = Trim4( Lower( values ) ) ;
firstvalue = Trim4( GetValue( allvalues ; 1 ) ) ;
firstcount = PatternCount( "¶" & Substitute( allvalues ; "¶" ; "¶¶" ) & "¶" ; "¶" & firstvalue & "¶" ) ;
newvalues = Trim4( Substitute( "¶" & Substitute( allvalues ; "¶" ; "¶¶" ) & "¶" ; [ "¶" & firstvalue & "¶" ; "" ] ; [ "¶¶" ; "¶" ] ) )
] ;

Case(
IsEmpty( allvalues ) ; "" ;
firstvalue & Substitute( suffixFormat ; "n" ; firstcount ) & "¶" & SummariseValues( newvalues ; suffixFormat)
)
)
