I just pasted the expression into one of my projects and it worked fine. You may just need to allow the expression to go onto two lines like so:<br><br>
PARENT("WIDTH")*PARENT("HEIGHT")*0.0464/<br>(PARENT("WIDTH")+PARENT("HEIGHT"))<br><br>Another way to shorten the expression is use #P instead of writing out "Parent"<br><br>
#P("WIDTH")*#P("HEIGHT")*0.0464/(#P("WIDTH")+#P("HEIGHT"))<br><br>Hope this helps<br><br>--<br>Karen<br><br><div class="gmail_quote">On Thu, Jun 26, 2008 at 4:28 AM, Prabhat Barnwal <<a href="mailto:prabhat.greenbuildings@gmail.com">prabhat.greenbuildings@gmail.com</a>> wrote:<br>

<br>
While writing an expression for window frame width of curtain walls in<br>
eQuest 3.61, I am getting 'Expression parsing error' saying the user<br>
expression is too long. The expression used is-<br>
default :<br>
PARENT("WIDTH")*PARENT("HEIGHT")*0.0464/(PARENT("WIDTH")+PARENT("HEIGHT"))<br>
<br>
How should I modify or change it?<br>
<br>
Are there provisions for creating local variable by arithmetic operation on<br>
present variables? For example, the length of this expression can be reduced<br>
, if I calculate perimeter of parent wall first and use that value directly<br>
in the expression.<br>
<br>
Any help will be appreciated.<br>
<br>
