You can:
Total Mixture Amount: Enter any positive number to express values in terms of actual measurement units rather than expressing measurements as proportions, that is all components sum to 0 and 1. The default value is 1.
Multiple totals (up to 5): Enter up to five positive numbers to perform a mixture amounts experiment.
Component Bounds Specified in Amount (lower and upper are the first total, if you specified more than one)
Name: Enter text to change the name of the components.
Lower: Enter the value of the lower bound constraint for each component.
Upper: Enter the value of the upper bound constraint for each component.
