Help me please!!!

I have a customer that used to have a search function in MS Word 2000 that allowed him to search the entire document for select words, and then it would highlight those words as it found them. However, a "computer guru" in the office decided to upgrade the computer and WIPE the entire hard drive thus deleting the macro/vba script - whatever it was - and now the customer wants this function back. I am a complete stranger to the programming world and I have to recreate this macro. I know that in MS Office, macros are created with Visual Basic for Applications. I have recorded a macro that finds onc instance of the word and higlights it. I need to loop this until it has found and highlighted all the words or text that I have preselected, then moving on to the next word. Here is a copy of the code that I have (genereated by the macro recorder). If anyone can offer pointers on how to loop this please let me know. Thanks.
