Create any modules or line items you might need in Modules in the model settings bar, then format the line item that will contain a link. Ensure the line item has a Text - Link data type.
Example
For example, if you want to generate a link to the https://myproducts.com website, add a formula to the line item that contains the link.
Type the following formula in the line item you want to use: MAKELINK("Click Here", "http://www.myproducts.com")
"Click Here"appears in the cell as a clickable link."http://www.myproducts.com"is the URL for the link.
