Doh! You caught me. I was looking so hard at my GetISLines function I missed my typo on the tal attribute. It should read tal:repeat not tal:replace. I've been playing with it. I think the error is coming from my script. I added a line "FY -=2000" and I got the same message but instead of the dash, I got a "-=". That tells me I'm calling my routine and it's giving the error. I've been breaking things down into small steps. <span tal:content="python:request.get('FY')"></span> prints the FY attribute from the URL correctly but so does this; <span tal:content="python:request.FY"></span> This tells me I'm on the right track and that this is the correct syntax for passing the URL attributes to my script. I'll keep playing with it. I've read through the page templates chapter a number of times. I've also read the advanced section along with the appropriate sections in my other three books but without specific examples on referencing the request attributes from within the tal statement, I just couldn't figure it out. It's not very intuitive for me having executable code in quotes. It goes against 20 years of habits and just throws my brain all out of whack. Thanks again.

Thanks again. Still no go although it looks like it's getting closer. I tried this;
<tr tal:replace="item python:here.GetISLines(FY=request.FY, Per=request.Per)">
To my programmer eyes, that looks like it might be correct.
To mine it looks wrong :-) In fact, you should get a Compilation Failed error when you save that page template. That's what I get here.
I neglected to mention why this is so. There are two general forms of tal statements: those that take only a TALES expression, and those that take an identifier followed by whitespace followed by an expression. tal:replace is one of the former, so the "item" identifier is syntactically incorrect and must be removed. Identifiers are not allowed for tal:condition, tal:content, tal:omit-tag, tal:on-error, tal:replace. Identifiers are required for tal:attributes, tal:define, and tal:repeat. I was about to suggest that you need to read the Zope Book introductory chapter on Page Templates. However, just having re-read it for the first time in a long time, I don't think it's very newbie-friendly at all. Maybe you read it already :-\ It skips too quickly through the basics, doesn't really explain some basic concepts, and gets you into writing python scripts too early, a topic which is covered more appropriately in later chapters. -- Paul Winkler http://www.slinkp.com Look!
