Hi - I'm getting this error message when I try to execute a MvCALL:

"Line 102: MvCALL: Runtime Error: Unable to open URL 'filename.htm': Unsupported protocol 'filename.htm'

I'm not familiar with the "unsupported protocol" error. Does this mean that it doesn't recognize the format of the file I'm calling?

The file I'm calling is a simple HTML file. Is it missing something critical in the head?

<html>
<head>
<title>Resource Page</title>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
</head>
<body>
A simple table with text.
</body>

Thanks for your help.

What is your code for the MvCALL?

<MvCALL ACTION="{'http://www.mysite.org/parallel/resources/' $ g.resource $ '.htm'}" METHOD="GET">
</MvCALL>

You have the method and action reversed. It expecting your "GET" first, which is why you're gettting the unsupported protocol error.

Are you referring to the order of the ACTION and METHOD statements?

I tried putting METHOD first. The error message disappeared, but it still doesn't open the file. :(

<MvCALL METHOD="GET" ACTION="{'http://www.mysite.org/parallel/resources/' $ g.resource $ '.htm'}">
</MvCALL>

Can you open it yourself with a direct URL?

Yes, and I've tried substituting URLs from other sites. This is driving me nuts. I've used MvCALL many times before, but right now I can't get it to open anything, even in a test file with contains little more than the call.

<html>
<head>
</head>

<body leftmargin=0 topmargin=0>

<MIVA DEFAULTMACROENCODING="entities">
<miva standardoutputlevel="html,text,compresswhitespace">

<MvASSIGN NAME="resource" VALUE=substring(lang1, 1, 2)>
<MvCALL ACTION="http://www.amazon.com" METHOD="GET">
</MvCALL>
</MIVA>
</body>
</html>

<MvCALL ACTION="{'http://www.mysite.org/parallel/resources/' $ g.resource $ '.htm'}" METHOD="GET">
</MvCALL>

I think you'll need form the link in the action by doing something like this:


<MvASSIGN NAME="l.url" VALUE="{'http://www.mysite.org/parallel/resources/' $ g.resource $ '.htm'}">
<MvCALL ACTION="{l.url}" METHOD="GET">
</MvCALL>

I believe when you pass a varable to the "action" there can be no literals. In other words when you used the curly brackets, Empressa expects a var.

Its working! I'm a new programmer and started this project by "cannibalizing" code I wrote previously. I neglected to pick up two important lines that I believe tell Empressa to evaluate the code and send it to the screen:

<MvASSIGN NAME="temp" VALUE="{glosub(s.callvalue,'<pre>','') }">
<MvEVAL EXPR="{ glosub(temp,'</strong>','</strong><br>') }">

With the addition of these two lines, the script is working.

Thank you for your suggestions and for hanging in there with me to work this through.

You need this...

<MvEval expr="{ callvalue }">

Before the closing </MvCall>
