Column A has numbers separated by dots to indicate level like this:

1.1
1.1.1
1.1.1.1
1.1.1.1.1

Column B contains a text description like this:

Description one
Description two
Description three
description four

Goal: indent values in Column B three spaces for the COUNT OF DOTS GREATER THAN ONE in column A, something like this:

Description one
Description two
Description three
Description four

Thanks in advance for your suggestions.
