Test Variable?

[Garrett Hylltun]

I'm getting an error in this code:

on openField
   if varCmdLineParamIn is not empty then
     put varCmdLineParamIn into varFilePathCurrent
[snip]
   end if
end openField


Type:  Expression: unquoted literal
Object:  FieldEditor
Line:   if varCmdLineParamIn is not empty then

In my "on openStack" I do declare the variable as "global  
varCmdLineParamIn"

I have no clue what is wrong or how to fix.  Anyone able to give me  
some help on this?

Thanks,
-Garrett
