[ic] If statement help

[interchange-users@icdevgroup.org (interchange-users@icdevgroup.org)]

The following code snippet is from the standard results.html page running
on version 4.8.6:

[if session browser =~ /mac/]
               <input type=submit value="[L]Buy now[/L]"

<input type=submit value="[L]Buy now[/L]"

onClick="this.form.mv_oi[item-increment].value='[item-code]'" border=0>

[else]
[if explicit]
    [condition]
        $cat = '[item-field prod_group]';
        return 1 if $cat eq "Training";
        return 0;
    [/condition]
<input type=image src="__THEME_IMG_DIR__reg_now.gif" onClick
="this.form.mv_oi[item-increment].value='[item-code]'" border=0>

[else]
<input type=image src="__THEME_IMG_DIR__buynow.gif" onClick
="this.form.mv_oi[item-increment].value='[item-code]'" border=0>
[/else]
[/if]

[/else]

[/if]

The code seems to run fine except for the first line returned in the search
always returns the " __buynow.gif" button (the [else] option from the [if
explicit] statement) when searching out a list of "Training" prod_group
items.  After the first line all subsequent lines show the correct button "
__reg_now.gif" in association with items from the "Training" prod_group.
 I am at a loss to explain this behaviour. Any ideas?

Thanks in advance,
