I have a database of chemicals and one of the entries is the MSDS number. I would like a hyperlink, pointing to the .pdf of the chemical, created when I enter the MSDS number. If the MSDS number is 1111 the .pdf file will be something like (\\servername\folder\1111.pdf). Is there a way to store \\server\folder\ in a string, append the MSDS number, and .pdf then store that in a hyperlink field. Any suggestions?
