adding a URL to a button

[#1]

I have a url that varies by customer.   The variable name is CUSTOMERURL

I've created a radio button to link to a website tied to the url but am getting an error message that it fails to load  (I'm using the OPEN URL in the Actions tab and simply point to the CUSTOMERURL variable).

The form of the url has no preceeding 'http://' or 'https://' and is read into Qlik as a character variable.     I can get a static website such as www.google.com to work but not for the url in CUSTOMERURL

Thanks

I use a full on button for this, and in the Open URL expression, simply put =varCustomerURL

Only seems to work with the preceding "=", but certainly, it does connect through to site

Hi Rick,

what's the error that you are getting when you press the button?

Trying adding http:// as follows in the URL windows, e.g.:

='http://'&CUSTOMERURL
