In your navbar template I noticed that you have this code below the the navbar line:
Code:
<!-- content table -->
$spacer_open
$_phpinclude_output
That should, if anything be above <!-- nav buttons bar -->. The spacer_open controls the StyleVars width (and other) settings. You can keep that if you make an adjustment in your Table tag by replacing:
Code:
<!-- nav buttons bar -->
<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="0" border="0" width="100%" height="25px" align="center" style="border-style:solid;border-top-width:1px;border-left-width:1px">
With:
Code:
<!-- nav buttons bar -->
<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="0" border="0" width="$stylevar[outertablewidth]" height="25px" align="center" style="border-style:solid;border-top-width:1px;border-left-width:1px">
As for your left and right borders you it located in the Body CSS definition. It should be in the Page CSS definition to make it appear right. I can't see the rest of your Body CSS definitions but if you still have the width setting of "750px" there remove it and place that in your Table Width settings in StyleVars.
The border guide in vB.com should work right if these changes are made.
