Input Field Reset

[#1]

I have the following input field.

I want to reset the values to existing Grade min values not zero

INPUTFIELD CustomMin, CustomMax;

Grading:

LOAD //GradeID,

     GradeMin,

     GradeMax,

     GradeMin as CustomMin,

     GradeMax as  CustomMax,

     Grade,

     GradingName

   from source

I guess you are asking how to initialize an INPUTFIELD to blank or any other default value with an action of a button.
