If uploading a file that was downloaded earlier in the flow from a Click command, pass in the variable set from the "Store downloaded file path in variable" field in Click
In order to use this command, you need to allow Browserflow to access files:
Click "Details" for Browserflow
Enable "Allow access to file URLs"
Browserflow does not yet support uploading files into <input> elements inside iframes
Finding the file upload element
On many sites, the file upload element is hidden, which means that it's not possible to select it using the "Select" button. In these cases, you can use Recording Mode to have Browserflow detect the correct file upload element.
