[SOLVED] Getting an error and as im new i don't know what to do

[adam291086]

this is the function where the error is

//setting up the ajax update part
function createXMLHttp() {
if (typeof XMLHttpRequest != 'undefined')
return new XMLHttpRequest();
else if (window.ActiveXObject) {
var avers = ["Microsoft.XmlHttp", "MSXML2.XmlHttp",
"MSXML2.XmlHttp.3.0", "MSXML2.XmlHttp.4.0",
"MSXML2.XmlHttp.5.0"];
for (var i = avers.length -1; i >= 0; i--) {
try {
httpObj = new ActiveXObject(avers[i]);
return httpObj;
} catch() {}
}
}
throw new Error('XMLHttp (AJAX) not supported');
}

 

 

this is the error

 

Error: missing identifier in catch

Source File: http://adamplowman.co.uk/Rubber_Duckie/moving.js

Line: 107, Column: 8

Source Code:

} catch() {}

put 'e' in catch so it reads

 

catch(e)

 

with the vode around it the same. This is provided the rest of the function is written to do what it's supposed to.

[adam291086]

that stopped the error, but i am missing something else as the ajax stuff is stopping the moving of objects around, this is all the page code you can see whats happening here http://adamplowman.co.uk/Rubber_Duckie/moving.php i want the box to move around and the database gets automatically get up dated

 

heres the js code

<!--
