Hi Lynn,
We're practically neighbors! I work at the University of Indianapolis.

This works for me:
master_page:
<html metal:define-macro="page">
<head>
<title tal:content="template/title">The title</title>
</head>
<body metal:define-slot="body">
This is Page Template <span tal:replace="template/title" />.
<p metal:define-macro="para">Plug some text in
<span metal:define-slot="text">here</span>.
</p>
<p metal:define-macro="condPara">
<span><span tal:condition="myTest">My TestResult</span>
<span metal:define-slot="text">this is from master..
</span>
</span>
</p>
</body>
</html>
slave:
<html metal:use-macro="here/master_page/macros/page">
<head>
<title tal:content="template/title">The title</title>
</head>
<body metal:fill-slot="body">
Totally Different Text.
<div tal:define="theInput request/theInput | default;
myTest python:theInput == 'hello?'">
<pre>
The input = '<span tal:replace="python:theInput">theInput</span>'
MyTest = '<span tal:replace="python:myTest">myTest</span>'
</pre>
<p metal:use-macro="here/master_page/macros/para">Plug some text in
<span metal:fill-slot="text">this slot</span>.
</p>
<p metal:use-macro="here/master_page/macros/condPara">
<span tal:condition="python:myTest">
<span metal:fill-slot="text">Should only show if theInput is
'hello?'.</span>
</span>
</p>
</div>
</body>
</html>

I think 'here' is the folder that the template is in.

hmmm.. it works for me....

I'll try to take a stab at converting this to ZPT as a learning
exercise. ;-)

I think this is basically your earlier question... if not let me know!
