get last month, set it as a variable and insert in script

The problem is that the 08 (and 09) are no valid numbers as a leading 0 tells the interpreter to treat this as an octal value and 08 (and 09 are no valid octal numbers)

This may be fixed for example in this way:

Code: Select all

set /a "bb=1%aa%-101"
