default setting if recordset is empty?

default setting if recordset is empty?

I have a map that gets its "markers" based on the users selection in a dropdown. This all works fine with some basic recordsets.

However, when the page is first loaded and there is no user selection, no map shows at all. But when i view source i can see it has loaded a single blank address from the empty recordset

How do i set the map to a default wide view over the country if the recordset is empty?

I am aware I can set a default "address" with another recordset on the first load, but I do not want an address to show as that is too specific, I want to show the wider area first with no markers on first load.

Any ideas?

can you send a copy of your google_javascript folder so I can take a look at the code. there should not be a blank entry if the recordset is empty, it should default to a map of palo alto.

also, cold you priovide a li nik so I can see the problem in a browser.

I see whats going wrong, an error is occurring if the recordset is empty. In the wagmp_map_2.php file, change line 145 - 262 to:

php:
