Error text

The third parameter to System Function Slice must be an integer or array of integers.

You have used one of these syntaxes:

 X[@I = n]
 Slice(X, I, n)
 Slice(I, n)

and «n» is non-numeric, or «n» is an array containing a non-numeric value.

This error seems to appear, but should not, when «n» is an array containing a Null cell.

Find the non-numeric entry, then figure out why it is non-numeric and fix that.

When «n» is an array, create another variable, temporarily, and define it as:

IsNumber(n)

replacing n with the «n» from your slice expression. Then view it to find where the value is non-numeric.

If you are having the Null problem, consider using this slice function:

 Function Slice2(X: Array; I: Index; n: positive orNull)
 Definition: If n = Null Then Null Else Slice(X, I, Max([n, 1]))
