  • Hi can you try without setting viewXml condition and check if its working fine. Like camlQuery.set_viewXml('<View><RowLimit>100</RowLimit></View>');

  • Still no luck after trying without query. Can you maybe help me understand why it brings back item 2 employees but every other option in the drop down brings back all the employees?

Try declaring collListItem outside the scope of the function and removing the 'this' keyword from the line:

this.collListItem = oList.getItems(camlQuery);

For example:

var collListItem;
function retrieveListItems(siteUrl) {
        var input = document.getItemById('siteDrop').value;
        var clientContext = new SP.ClientContext(siteUrl);
        var oList = clientContext.get_web().get_lists().getByTitle('Employees');            
        var camlQuery = new SP.CamlQuery();
        camlQuery.set_viewXml(
            '<View><Query><Where><Geq><FieldRef Name=\'Site\'><Value Type=\'Text\'>'+input+'</Value></Geq></Where></Query></View>'
        );
        collListItem = oList.getItems(camlQuery);            
        clientContext.load(collListItem);
        clientContext.executeQueryAsync(
            Function.createDelegate(this, this.onQuerySucceeded), 
            Function.createDelegate(this, this.onQueryFailed)
        ); 
    }
