I'm creating in inventory file for the products we'll receive each year. In this file a lot of information has to be available (supplier, product #, lot #, has the package insert been verified....). To make the process easier, I created a data base file that contain these informations and in the inventory file I use Vlookup formula to populate the inventory but I have a problem with one formula for a hyperlink. Since the package insert for the product has to be retreived from the web site of the supplier, I use the following formula =hyperlink(iferror(vlookup($B273;'W:\DSMC\6.0 Laboratoires\1-Régional (tronc commun)\G6 – Ressources matérielles\Base de données\[Catalogue 2023.xlsx]sheet1'!$A:$E;5;FAUX);"")). The formula is "working" the web site address appears but when I click on it the web page does not open unless the data base file is open. Does any one have a solution?
