Search and display a record on a userform

Hi everyone, back again.

I have been steadily working on my project, and the next stage I was looking to implement a search and display function.
The document is a register of businesses, which is usually well into the 100's in terms of number of records, so I wanted a nice and easy search function where someone can type any key word and it will pull up all the associated records - eg. 15 records found, and be able to cycle through them or select one to display in full based on name, owner, and Ref number.

It needs to be displayed in a user-form type output so that the information can be easily be summarised for the user, I don't want them messing about with any of the data in table, even if it's just looking. The existing excel document which has been in use by myself and a few others was pretty much destroyed because people were entering and modifying data willy-nilly, so I am doing this redesign with userforms and macros to make it easy for those who are less proficient with technology (and so that they don't destroy any formatting or mess up entries).

A copy of the document is attached for your perusal. Links to useful resources and other threads are also appreciated. I want to be able to understand the code and not just have things done for me.
