problem sending search query '%%'

[webdreamer]

Hi guys,

from flash i am sending
searchLets.php?goSearch=letPostcode LIKE 'g45'
Works fine and does what it should.
But if i send
searchLets.php?goSearch=letPostcode LIKE '%g45%'
My broswer(I.E) dosent like it.

My AS code

seBT.onRelease = function() {
	if (mmLoose.getState() == true) {
		goSearch = mmSearch.getSelectedItem().data+" LIKE "+"'%"+theSearch.text+"%'";
		searchLets(goSearch);
	} else {
		goSearch = mmSearch.getSelectedItem().data+" LIKE "+"'"+theSearch.text+"'";
		searchLets(goSearch);
	}
};

Any suggestions?

Cheers
Paul
