Minitab GLM (General Linear Model) - Problem with recognition of Level

Hi,

I'm a newbie here. Anyway, I am analyzing my data with three factors with different levels.

However, I'm having problem with one of my factors - Type of emulsifiers. One of the level is Tween80. When I run the GLM, it kept recognizing it as two different Tween80. Why is that?

This is how it'll appear:

General Linear Model: IFT versus Oil, Emulsifier, Lipase

Factor Type Levels Values
Oil fixed 3 CO, OO, SBO
Emulsifier fixed 6 Lecithin, NaCN, nil, Tween80, Tween80, WPI
Lipase fixed 3 inactivated, none, RML

My guess is that you have typed them differently. Like Tween80 and Tween8O. If you zip your file and attach it, we can check.
