[JS] Eval problem with scriptUI

Question

Hello,
I want to build an scriptUI Interface with a specific group of buttons.
This group will be repeated accordingly to a an external txt file (telling the script how many groups are needed).
My script uses a for loop in the dialog construction like this :
for(i=0; i<n; i++)
     //Repeat the group of buttons with i as an ID;
     eval(addBtn(i));
to get the construction of the button, I created a addBtn(btnId) function.
It returns the code string to create my group of buttons with i as an ID.
function addBtn(btnId)
        myBtnString = "rapidDlg.Group";
        myBtnString+=String(btnId);
        myBtnString+=" = rapidDlg.add('group',undefined); ";
        myBtnString+= "rapidDlg.Group";
        myBtnString+=String(btnId);
        myBtnString+=".alignment = ['left',' '];";
        myBtnString+= "rapidDlg.Group";
        myBtnString+=String(btnId);
        myBtnString+=".checkBoxItem = rapidDlg.Group";
        myBtnString+=String(btnId);
        myBtnString+=".add('checkbox',undefined,undefined);";
        myBtnString+= "rapidDlg.Group";
        myBtnString+=String(btnId);
        myBtnString+=".aFile = rapidDlg.Group";
        myBtnString+=String(btnId);
        myBtnString+=".add('button',undefined,\'a File\');";
        myBtnString+= "rapidDlg.Group";
        myBtnString+=String(btnId);
        myBtnString+=".aFile.size= [245,20];";
        myBtnString+= "rapidDlg.Group";
        myBtnString+=String(btnId);
        myBtnString+=".removeItem = rapidDlg.Group";   
        myBtnString+=String(btnId);
        myBtnString+=".add('button',undefined,\'-\');";
        myBtnString+= "rapidDlg.Group";
        myBtnString+=String(btnId);
        myBtnString+=".removeItem.size= [30,20];";
        return myBtnString;
But my loop doesn't seem to wok, and as the dialog appears, my groups are not created :-(
Am i wrong using eval() or do I misuse it ?
Thanks a lot for your help :-)

Dave,
Thanks for the reply.
I'm not sure what you mean by "convert the references on the fly." You mean find a way to advance two characters forward and tag that? In the script I submitted here I am only searching for "abc," which of course I would not search or at all  in real life. The script uses grep to search for about twenty different typographical errors that typically appear and tags them all.
Reiterating backwards seems, at first sight the way to go. But I haven't a clue as to how to reverse the order of the stories. I can get an array of stories, and array.reverse() them, but am not sure how to then make the script put this reversed order into the xml structure. Any hints?
There, of course is bigger problem with the stories. If the document is written with one story created after another then the order of them is top to botom. But if say a text frame edited into the middle of all this, that story is still the last one in the xml structure. At least in one test, that was so. Maybe the way to solve this is to build an array of stories that have as one xml attribute the page it first appears on. Then order the array according to that attribute.
Any advice you give will be appreciated.
Thanks,
Tom
