HI Jason, many thanks for the swift response.
Unfortunately though that doesn't appear to have made any difference.
Below is the code I have in the form which I've amended as you suggested...
<label>
<input <?php if (!(strcmp(((isset($_POST["search_usage[]"]))?$_POST["search_usage[]"]:""),1))) {echo "checked=\"checked\"";} ?> type="checkbox" name="search_usage[]" id="search_usage_0" value="1" />
Light</label>
<label>
<input <?php if (!(strcmp(((isset($_POST["search_usage[]"]))?$_POST["search_usage[]"]:""),2))) {echo "checked=\"checked\"";} ?> type="checkbox" name="search_usage[]" id="search_usage_1" value="2" />
Medium</label>
<label>
<input <?php if (!(strcmp(((isset($_POST["search_usage[]"]))?$_POST["search_usage[]"]:""),3))) {echo "checked=\"checked\"";} ?> type="checkbox" name="search_usage[]" id="search_usage_2" value="3" />
and below is what is being displayed in the comparison list additions of the search script...
$WADbSearch1->addComparisonFromList("search_usage","search_usage","AND","=",1);
The "AND" is there as I have more groups of checkboxes within the form but it kind of made sense to just highlight one for the moment. Basically I have a list of products which have all been assigned a level of 'usage' - 1, 2 or 3 - which is recorded in the database in a column named 'search_usage' and I'm giving the visitor the chance to see any combination of machines, ie Just those with level 1 or those with level 1 & 2.
The form is functioning correctly in that it is displaying the right results but we're just not seeing the original checks in the boxes of the search panel.
Again, any guidance would be greatly appreciated.
Kind regards
Paul
