How do I display one Shipping method in standard shipping module?

[jmccann]

Hi,

Im using ovelapping Zip Codes/Post Codes and becuse of this I get two Shipping Methods displayed.
I'm not that php savvy and not sure what part of coding to change. How do I get just the first Shipping method displayed?

I think its in the function (?) :
while($dbr->next_record()) {

around line 63  that needs to get changed.

Here is the displayed output:

Please select a Shipping Method!
