Do you mean something like this:

$count+=1;
if ($$hashRecordPtr{"price_product$count"} ne "" ) {
  print "<tr bgcolor=\"#EDEFF5\">"; 
  if ($$hashRecordPtr{"connection${count}_description!} ne "") {
    print<<"CONNECTION1";
<td valign="middle" align="center" width="78">$$hashRecordPtr{"connect
+ion${count}_size${count}"}</td> 
    CONNECTION1
  }

  # etc...
}

Note that in some cases I've had to use ${varname} rather than $varname in order to disambiguate the variable name from the rest of the string.

For future reference, it's helpful if you create a short extract of code which demonstrates your problem. And if you clean your code (add indentation - stuff like that) so that it's easy to read.
