Ran into this problem today, have to define the values within the ui_infield command
I define them all in the master as arrays, one for integers, one for strings, and one for picture names (with the same amount of rows as the other two) can just be empty strings.
In the parameter I attach the values{2} with the integer and string arrays
then in the ui i use this command.
UI_INFIELD{3} Parameter, x, y, w, h, 8, "", 1, 1, 0, 0, 0, 0, PictureArray, StringArray, IntegerArray
I forget what the ones and zeros are for....
Good Luck.
