{This is not a valid rate value.}For Work resources, type the rate amount, a slash (/), and the abbreviation for the time period at which the amount is earned, for example, \"10/h\". 

For material resources, type the rate amount alone; for example, \"12\". If your Material label is \"gallon\", this would mean \"$12/gallon\".
