Hi all,

i hav a small problem

i m duplicating a moviclip

for (i=2; total\>=i; i=i+1) {  
duplicateMovieClip(1, i, i+16384);  
eval(“xpo” + i)= getProperty(1, \_x) + (i - 1) \* 18;  
setProperty(i, \_x, eval(“xpo”+i));  
}

but when i m exporting it error is coming

**Error** Symbol=Symbol 15, layer=ActionScript, frame=1:Line 7: Left side of assignment operator must be variable or property.  
eval(“xpo” + i)= getProperty(1, \_x) + (i - 1) \* 18;

i think my eval() syntax is right but y this error is coming i do not know.

get rid of the old coding!

use these **simple** 5 lines to copy and assign a new x value

```php

total = 4;
for (i=0; i<total; i++) {
	newObject = _root.sourceObject.duplicateMovieClip("newname"+i, i);
	newObject._x = _root.sourceObject._x+55*i;
}

```

check the attached .fla for more details
