    Hi guys,I need a script (either PHP or Javascript) that can curl or grab all the usernames from a website. (It can be Greasemonkey or anything). I don&quot;t expect to pay much since it will be a very easy script that takes you 1-3 hour to do. I&quot;m way too busy to deal with this now that&quot; why i posted it here.The website structure is like this: Question lists page --> Questions page --> poster&quot;s username insideI will let you know the website if you think you can do this.

    Hi David,Another calculator for you.The calculator calculates the loss of superannuation in personal injury litigation.Employers make superannuation (like pension) payments on behalf of their employers. It is currently 9% of gross earnings but will increase over the next few years.I have attached the vb code that we use to calculate the super. note error in function should be &quot;endyear&quot; not &quot;yearend&quot; in parameters.I would like you to join our lawyers section free and see how this page works. is almost the same type of calculator using the same variables. I have attached an excel spreadsheet showing how it works.The difference is that the years will need to keep on looping for each year as the rate changes. The tax rate is 15% flat.Once we have this report working, we will be able to add this report to the future eco loss report via a checkbox.

    Hi, i have a tool/script which currently does the following:1. It parses rss sources: an stores the items: It can count the items or count the number of certain keywords contained in the items for a certain date: It lets me display the data in a chart: can watch the how-to video here: you wish you can play around with the tool here: id:test[ät] pw:thisisatestNow i would like to use my tool to collect and display stock quote data too. That means:1. You will have to add the option to parse stock quotes feeds (e.g. we can use yahoo finance; e.g. You will have to adjust the db for such data, storing stock&quot;s current price/close and volume values for each day/during the day3. You will have to integrate the ability to show these data in the same chart (maybe it will be neccessary to replace the currently used charts with highchart highstock js, since the have cool options to use different y-axis)That&quot;s basically it. The whole project is written in PHP ans some JS and uses MySQL. I&quot;m looking for someone who is experienced in data parsing projects.Looking forward to your feedback.

I already have a working version of the software but it only works as a standalone page, I want to input the actual code onto any page I want without any errors. There will need to be an admin section where I can change certain criteria to fit different pages etc. Essentially, this will be a basic variation of an existing script that I will provide.This should be very easy for someone who knows what they are doing as I will be providing a working script.

    Need some urgent help to fix a few things on our website. This should take a few hrs for the right person.The coupon feature on our website does not properly. We need the coupon code entered applicable to only the costs of the item and shipping costs or Tax cost should not be included.Example: If the cost of the item is $35 and the coupon code is worth $45 then the cart will have a negative balance of -$10. If the customer wants to checkout then he will have a -$10 in his cart and when he is about to checkout then he will select a shipping method and if shipping cost is $5 then that $5 must not be included in the coupon redemption. The coupon must be applicable only to the cost of the items and customer must still pay the $5 for shipping.I need an import option in the admin where we can import any number of coupon codes to the admin from an excel sheet. The coupon codes should be valid only for one time use.If the customer redeems $35 from the $45 then he must redeem the $10 left at the same time or loose the $10.There are a few other tasks that are needed which I will explain as we get started. Must have good experience and good feedback.
