I need to authenticate users with our backend Caspio database, so trying to pass parameters to Open URL. Using:

APPEND_URL_PARAMETERS(“”, { EM: appVars.email_address, PW: appVars.user_pswd})

Should return a URL something like:

But instead, it’s inserting a / between login.html and ?, like this:

So the link goes to a 404 page instead.

Does anyone have any suggestions on how can I get rid of that extra / at the end of the URL?
