Auto fill introducer field on website

Hiya, I introducer business to? <[login to view URL]> You will see that each client has to input my agent key of? ZAR1/DML/001/000 in the relevant box. Clients don't always remember to do this which results in lost sales. Is it possible to create a script or something so that when? a client? clicks on a link on my main website, my agent key is pre-populated in the box and simulates the pressing of the "Start LoanCheck" button so the client has the experience of going straight the checking system via my hyperlink? That way the client wont see the agent key box and all clicks will be correctly registered to me when they go via my link. Many thanks ## Deliverables Please make this easy to install on my website as I'm not an expert. Cheers
