I would love to find out how to do some basic math using data from the cms.

for example..
I have a section for members that has 4 ratings.

each rating has a max of 5 stars. in the cms I have an area to choose from (0-5)

I need to figure out how to code this formula:

members total Selected Stars divided by 25 (which is the max stars) x 100 = Rating

so for example:

Member A:
quality: 3 stars
communication: 3 stars
professionalism: 4 stars
availabilty: 2 stars
total stars: 13

13 divided by 25 x 100 = 52 Rating

Hi,

No problem. Do you have a PHP file that is currently outputting the star information without the rating? If so, could you please attach that file? That way we can give you a much more concrete example.

Thanks,

Hi,

Give this a try:

<tr>
<td height="40" align="left" valign="middle" class="ash">Integrity Level</td>
<td width="35%" align="left" valign="middle"><div id="meter"><div style="background-color:#71B10E; height:10px; width:36px"></div></div></td>

<?php
$starTotal = intval($memberRecord['professionalism']) +
intval($memberRecord['communication']) +
intval($memberRecord['quality']) +
intval($memberRecord['expertise']);

$rating = ($starTotal / 25) * 100;
?>

<td width="29%" align="left" valign="middle"><?php echo $rating;?>%</td>
</tr>

Hope this helps
