I've never had a problem with this by u= rl'ing the variable if there's a chance it will contain an exclamation point= , equal sign or some other comparison symbol, which would cause a false comp= arison. If the variable is a known quantity, such as a variable you feed it f= rom a form value or otherwise explicitly set (as it appears to be here), the= n there's no need to waste your time with unnecessary [url]ing. Another simp= ler way is to reverse the comparison:
[showif =3D[selector]]
=
This way, even if it is something that could contain problematic c= haracters, they will come after the =3D and not cause a problem.
I'm curious if this isn't working, or if you are just wonderin= g out loud before coding it.

Hi All,
I am having an 'age-old' problem with webDNA.
I want to use a= showif tag with an empty variable.
I've read some of the arch= ives, but they don't seem to apply.
This works:
[showif= [selector]=3Dhome] [include home_page.inc] [/= showif]
[showif [selector]=3Dlocal] [= include local_page.inc] [/showif]
How d= o I make this work?
[showif [selector]=3D] [include bla= nk_page.inc] [/showif]
Thanks fo= r any assistance.
