Bear in mind that:
You cannot use relative references in Conditional Formatting criteria for color scales, data bars, and icon sets.
You may introduce conditional formatting to each cell on column H one by one, i.e. format 9 times. In each cell, after selection of icon sets, go to "Edit rules",
on the Green icon row, choose when value is ">",choose Type "Formula", value is "$G$n" (where n is the current row number); on the Yellow icon row, choose when value is ">=", choose Type "Formula", value is "$G$n".
After clicking OK, the cell would be able to display the 3-colour icon based on the comparison of two cell values.

Another way is to conditionally formatting the cells with red yellow green colours.
