Thanks Ray,
That got it working.
I used <input <?php if (in_array("B4NR",$InfractionsArray)) {echo "checked=\"checked\"";} ?> type="checkbox" name="B4NR" id="B4NR" value="1" class="formCheckboxField_Standard" title="Please select an infraction" />
You had it "1",$InfractionsArray)) I assumed that would work if I was just using numbered items. I put in the checkbox name instead and it works perfectly.. Now to get it to update.. Thanks again.
