Warning Message

The first parameter, «k», of Function Combinations(k,n) cannot be larger than the second parameter, «n».

Cause

You have probably inverted the order of the parameters to Combinations. How many sets of size 3 are there among a collection of 5 elements? That would be Combinations(3,5). Mathematical notation for combination often appear as

[math]\displaystyle{ \left( \begin{array}{c} n \\ k \end{array} \right) }[/math] or [math]\displaystyle{ _nC_r }[/math]

which becomes Combinations(k,n) in Analytica.
