Clears a range of repetitions for a specified variable

Sample Input:

ClearRepeatingVariable ( "$$test" ; 1 ; 3 )

Sample Output:

None... but if $$test, $$test[2] and $$test[3] existed previously, they no longer will.

/* Author: Kevin Frank Last revised: 11/11/11 Purpose: Clears the specified range of repetitions for a specified variable Example: ClearRepeatingVariable ( "$$test" ; 1 ; 3 ) ...(make sure to enclose the variable name in double quotes) ...this will clear $$test, $$test[2] and $$test[3] (there is no negative consequence if they don't exist) Inspired by and based on Sam Barnum's JoinRepeatingVariable CF */ Let ( startIndex = Max ( 1 ; startIndex ) ; Evaluate ( "Let ( " & variableName & "[" & startIndex & "] = \"\" ; \"\" )" ) & Case ( endIndex < 0 ; "" ; endIndex ≥ 0 and startIndex ≥ endIndex ; "" ; clearRepeatingVariable ( variableName ; startIndex + 1 ; endIndex ) ) )
Then copy & paste into FileMaker Advanced's Edit Custom Function window.

Again,

If I

ClearRepeatingVariable ( "$$test" ; 3 ; 1 )

that would only clear rep 3?
