Hi folks, here is the set up. I’m working with three files. Main.swf which contains navigation.swf in a blankmc, empty mc called mcContent where navigation sleclected materials are loaded.
In the navigation.fla here is the code
[AS]trace(“now defining global”);
\_global.loadFile\_str = strPicName;
trace(“global defined as”);
```
trace(_global.loadFile_str);
```
\_root.mcContent.loadMovie(“monthlyreports.swf”);
[/AS]
which leads to the trace results of…
[AS]now defining global
global defined as
images/cbookings.jpg
[/AS]
when i do a trace of loadFile\_str in the first frame of monthlyreports i get a undefined. I have tried trace(loadFile\_str) and trace(\_global.loadFile\_str)
I also noticed that if i define the global on the main movie ( it maintains the global variable, the navigation fla will not overwrite it) not sure if that helps anything but i thought i let you know.
Thanks for any help.

Hi,
It works for me.
i’ve made a movie called navigation.swf and other monthlyreports.swf (as yours =) ) as follows…
```auto
// first frame in **navigation.swf**
trace("now defining global");
_global.loadFile_str = "strPicName";
trace("global defined as "+_global.loadFile_str);
this.loadMovie("monthlyreports.swf");
```
and…
```auto
// first frame in **monthlyreports.swf**
trace(loadFile_str+" (located in external swf)");
```
Output window displays…
```auto
now defining global
global defined as strPicName
strPicName (located in external swf)
```
…and all works fine 😉
sample files below…

Thanks PCMan,
Maybe it was a bugish kind of a thing. Its not the first time i’ve had something work in one file and not in others. I’ll give your files a shot and hopefully it works!
Thanks again

heres a thought…
i got the impression you were trying to set the global variable to a local variable called _strPicName_…
does _strPicName_ actually have a value??
meh… just a thought 😉
Prophet.

Prophet: yes strPicName has a value something like “home.xml”
PCMan: You attached .swf’s and not .fla’s so I can’t see it working as I want it to.
I still have the problem. Anyone have anyother suggestions? Here is the latest info…3 files. Home, Nav, Content
Home AS Code:
[AS]if (\_global.loadFile\_str == undefined) {
trace(“default aboutus”)
\_global.loadFile\_str = “aboutus.xml”;
}
\_root.mcContent.loadMovie(“content.swf”);
\_root.mcNav.loadMovie(“navigation.swf”);[/AS]
Nav AS Code:
[AS]Actions.ldmovie = function(strFilePathName){
\_global.loadFile\_str = strFilePathName;
\_root.mcContent.loadMovie(“content.swf”);
trace("nav: " + \_global.loadFile\_str);
};[/AS]
Content AS Code:
[AS]trace("Content: " + loadFile\_str);[/AS]
Trace output :
[AS]default aboutus
Content: aboutus.xml
nav: directions.xml
Content: aboutus.xml[/AS]
