ok. i understand the fixed cost and work x standard rate part ...

now for the material, i went into my resource sheet and saw that there is a material type there. when i did that i can only enter value to standard rate. a single lump sum value for that material. so this means, material may only be a lump sum entry correct?

for the cost resource type however when i changed the type to cost, all fields just closed for entry. i can not enter any value anywhere. Or do i need to insert a certain column?
