Hi all

Got a quick issue I could do with some help on. I cannot remember how to set up a search function on a website. I did know how to do this but its been a long time since i did web development, ive been concentration on programming and have lost touch abit with web design and implementation. Any help would be much appreciated as my search box is rather useless at the moment. I only wanna be able to search within my site. Thank you in advance you lovely people. JustinGH
