    “I showed Daniel a website that had a similar calculator on it and explained that the owner of that site used java script. I went over the fact that I needed it to function the same AND add a few things. He said not a problem and that he used PHP but that it was "just another language" so I proceeded. It was only at the end did I realize that he would not be able to do several of the things that I needed and that no matter how hard he tried, PHP would not create what I needed. I paid him because he worked to do what he could but that from the beginning He was the pro and I'm the customer and if he wasn't going to be able to deliver what I needed, as I needed it he should of said he just cannot and I could of found another freelancer. Now I have paid good money for something that is not attractive to my customers and doesn't work correctly. I now have to hire another person to redo what he has done. Choose your freelancer wisely and when you specify a language don't let the freelancer say they use a similar language and it will be ok because it won't!!!!”
