[Zope] dtml-if problem

[Eric Walstad]

Hi Terry - Disclaimer: I'm a Zope Newbie...
Here's what I'd try:

Length of the value of Area is: <dtml-var
expr="_.len(Area)"><br>
Length of the 'strip'ped value of Area is: <dtml-var
expr="_.len(_.string.strip(Area))"><br>

If you see somethinkg like:
Length of the value of Area is: 4 (or more)
Length of the 'strip'ped value of Area is: 3
when you view the DTML method, you have either white
space in your Area variable or a linefeed charater,
or...

If that's the case, here's a working if statement:
<dtml-if "_.string.strip(Area)=='BIS'">

You could also try:
<dtml-if "_.string.find(Area, 'BIS')>0">
which will search for an instance of 'BIS' in the
value of the Area variable

Hope it helps,

Eric.

// The following will not evaluate true and I am
stumped again.
// 
// <dtml-if "Area == 'BIS'">
// 
// Area is a variable I am passing to my method and I
want to check to
// see if the variable is set to BIS, but it never
returns true even
// though a <dtml-var Area> displays BIS.
// 
// Confused as always,
