Modify Base64-encoded button formulas
Some customers like to use Base64 encoding for their URL to mask the parameters. This is optional, not required.
This page shows how to change the Base64-encoded formula URL button code.

In order to remove the JavaScript code from the button formula URL that's Base64-encoded, please follow these steps.
In the first line of your button formula, copy and paste the code below between the slashes. You must copy and paste this exactly as it appears below.
URLRoot () & "/db/" & Dbid () & "?a=dbpage&pagename=JuicedAddonPopup.html&url=" &Copy this line of code exactly as shown above.

Remove the JavaScript code from line 2, as shown below.
Note
We're showing two examples of how the second line could be written. There are different variations of how the JavaScript could be inserted in your formula.

After you remove the JavaScript code, the button formula looks like the example below.
Note
Keep the quotation mark at the start of line 2 so the URL is still in quotes once the JavaScript is removed.

Remove the bottom highlighted lines from the formula as shown in the screenshot below.
