Conditional coloring of Excel cells, based on adjacent cell values?

Hello: I wish to color a column of cells containing numerical values,
based on significance (p-values) in a second column.

If the p-value is less than 0.05 (p < 0.05), then I want to color the
adjacent cell (in the first column) according to the code pasted
below.

If the P-value is equal to or greater than 0.05 (P >= 0.05), then I
want to leave the adjacent cell (first column) uncolored.

Here is the VBA code, that I copied from the web and pasted into my
worksheet (rght-clicking the small tab at the bottom, and selecting
the "View Code" selection.

Thank you in advance for your help, appreciated! Sincerely, Greg S.
