Conditional Formatting- Extending To Whole Row

Using the oldest version of Excel (200) I have to insure all members of our squad can utilize this function. Trying to format a whole row based on one cell in that row that reports number of days till the next physical. My formatting works correctly for the initial cell, but does not extend correctly to the rest of the row. I am using the "Cell value is" option. I used:

Cell value is between 1 and 365 - color green
Cell value is between 0 and -30 - Color Yellow
Cell value is between -31 and -365 Color Red.

All cells with no value in it are yellow, even if the original formatted cell is another color and the cells that have other data in them such as the physical date, have no color in them regardless. read and tried several approaches from other threads with no good results. considering the results from those threads, I am curious if it has to do with it being an older version.
