Coders any idea?

[Pennies4me]

$ad['class']=="G","$ad[pamount] X.P",
Trying to place this code, into

               <td width=100>".iif($ad['class']=="P","$ad[pamount] Points","$settings[currency]$ad[pamount]")."</td>

To offer 3 incentives to PTSU. I have coded the Admin tools and functions. They work now all i need to do is change the display.
Do i use another iif command? Or just slot the bit of code in between the points and cash? Or is it a different part altogether?

As you can see my PHP knowledge is limited(ish)

".iif($ad['class']=="P","$ad[pamount] L.P")."".iif($ad['class']=="G","$ad[pamount] X.P","$settings[currency]".number_format($ad[pamount],2))."

Botched it myself...
Seems to work.
Any input is good If i have done it well i will be shocked
