Beginner HTML / CSS Question. HTA - Only show content if something = true?

Experts,

I've been playing with a locally developed HTA.  The coding isn't clean, as I'm only in it currently to learn the process...  But, I'm trying to accomplish the following, and can't find any information catered to somebody at my "level":

In the HTA *posted below, we're going to be implementing it as a logon banner.  It's looking great, but in this processes, if it the script fails to map drives, etc - I'd like to display that to the end-user as a warning.

I've got the warning area all worked out (at least in function) - but I'm not seeing how I could make it so that it doesn't show at all, unless a condition is met.  (ie. I'd like the warning to show up if there's a global variable set for the error, and not show up if there aren't any errors.)



Sorry if the question is confusing - I'm new to HTML / CSS and don't know much about it .

In your HTML section, add an If-Then around the 'warning area.

I'm not sure if this is the right way to check for the error condition you are looking for, so it may need to be modified...

<% If Scope = "Error" Then %>
<div class="warning"><img src="\\***\Images\Warning.gif" align="left" hspace="5" vspace="5"><textarea name="OutputError" ID="OutputError" style="font-family:Arial" style="background-color:transparent" style="color:#FF0000" rows="6" cols="100" readonly="true"></textarea></div>
<% End If %>

Thank you very much for the assistance.

I actually ended up going the way of VB, and having the div control hidden, but then having VB change that value within CSS to "block" if the conditions were met.

Much appreciated on the help!
