ADO Select statement clobbers html

I'm using ADO and MS Access. It seems that as I add to the number of fields that I evaluate, there is a point where I exceed some buffer and I clobber a portion of the html; starting at the end of the html.
Does anyone know of this problem? Is there some space I should be initializing or limiting?

Here is an example:

$first=$DataRs["first"];
$last=$DataRs["last"];
$initial=$DataRs["initial"];
$ss=$DataRs["ss"];
$address=$DataRs["address"];
$city=$DataRs["city"];
$state=$DataRs["state"];
$zip=$DataRs["zip"];
$email=$DataRs["email"];
echo "<br>2. sql = ".$email;
$phone=format_phone_us($DataRs["phone"]);
$license=$DataRs["license"];
$rCity1=$DataRs["rCity1"];
$rPhone4=format_phone_us($DataRs["rPhone4"]);
$statement=$DataRs["statement"];

About half the html gets wiped out.
If I remove the line - $rCity1=$DataRs["rCity1"]; (third from bottom), the html survives.
I get slightly different results when I remove different lines. I'm sure something is getting clobbered.

 

I just saw mjp',s comment on my other thread, and I agree I should be using mysql.
I'm trying to figure out a reasonable migration from ms access and not doing well. I'm migrating a classic asp site.
I have seen some size parameters in the ADO manual, but don't have it figured out yet.
