Error #4266
This is not a valid Units value.
For Work type resources (such as people or machinery), type a positive number between 0 and 60,000,000 (or 6,000,000,000 percent) with up to two decimal places.
Material type resource assignments (such as consumable materials like fuel or cement) can be either fixed or variable. For a fixed material resource assignment, type the units value alone. For example, "10" would mean "10 tons", if your material label was, for example, "tons".
For a variable material resource assignment, type the units value, a slash (/), and the abbreviation for the time period at which the unit value is accrued. For example, "12/w" would mean "12 tons per week".
