[BNM] Flash text variables issue

[Paul Booth]

Hi Rob,

Glad you found a solution. A trim function is used to remove leading and
trailing whitespace from a string but it looks like AS doesn't include a
trim function as standard (I assumed it would). Here is a link to a class
which adds this
functionality<http://theolagendijk.wordpress.com/2006/06/30/experience-with-actionscript-20/>
if
you need it in the future.

Cheers,

Oaul.
