Highlight all the cells E3:E200 and then click on Format | Conditional
Formatting and in the first box select Formula Is rather than Cell
Value Is, then enter this formula:
=AND(E3>0,E3<70)
Click on the Format button and select Red and Bold then OK. Then click
Add, and for your second condition you can select Cell Value Is, Equal
To, 0 (zero), then click the Format button again, Patterns tab and
select your background colour. Then OK your way out and this will now
have been applied to all cells that you highlighted.
Hope this helps.
