VBC09358 — For control variable already in use

Severity: Error · Family: VBC (static semantics / abstract syntax tree) · Source metadata: VBCompileErrorInfo

A loop is controlled by the variable of a loop it is nested in.

Each For loop counts with its own control variable: a loop nested in another cannot count with the same one, which the outer loop counts with.

MS-VBA reports the same error, with the same message (recorded in Excel).

How it is raised

Situation	Example	Resolution
The same variable in two nested loops.	`For i = 1 To 2` … `For i = 1 To 3`	Give the inner loop a variable of its own.
