Automate fractions using a script.

Question

Hi,
i was looking to automate the layout of fraction with a script.
The script has to change 1/200, 1/20, 1/33 to fractions:
When we do it manually, we insert an anchored textframe which contains a 2 row/1 column table.
We then copy the numbers in the cells.
I found the script below in a previous discussion.
But i get an error 30480 on line 14.
I'm a bit of a dummy when it comes to scripting, so can anyone tell me what's wrong with it?
var theDoc = app.activeDocument;
var myTableStyle = "tabelbreuk"; //MUST  be set!!
var myCellStyle = "celbreuk"//MUST  be set!!
var myObjectStyle = "TF-breuk"//MUST  be set!!
app.findGrepPreferences = null; 
app.findGrepPreferences.findWhat = "\\d+/\\d+";   //should find all occurrences of number(s) + / + numbers(s)
var searchResults = theDoc.findGrep(); 
for(var i = searchResults.length -1; i >= 0; i--)
var foundFraction = searchResults[i];
var newTextFrame = foundFraction.insertionPoints[0].textFrames.add({geometricBounds: [0,0,foundFraction.leading, foundFraction.parentTextFrames[0].geometricBounds[3] - foundFraction.parentTextFrames[0].geometricBounds[1]], appliedObjectStyle:theDoc.objectStyles.itemByName(myObjectStyle)});
var tmpDest = foundFraction.move(LocationOptions.AT_BEGINNING, newTextFrame);
var fractionTable= tmpDest.convertToTable('\r', '/', 1);
fractionTable.appliedTableStyle = "tabelbreuk"
setTableWidth(fractionTable);
newTextFrame.fit(FitOptions.FRAME_TO_CONTENT);
function setTableWidth(fractionTable){
    var widthArray = [];
        var allCells = fractionTable.cells;
   for(var c = 0; c < fractionTable.cells.length; c++){
        var aCell = fractionTable.cells[c];
                aCell.appliedCellStyle = "celbreuk"
widthArray.push((aCell.texts[0].endHorizontalOffset - aCell.texts[0].horizontalOffset) + aCell.leftInset + aCell.rightInset)
widthArray.sort(Numsort);
fractionTable.width = widthArray[widthArray.length-1]
function Numsort(a,b){return a - b}
thx

Hi Ariel,
thank you for your answer.
But the fractions made with the openType feature are not the kind of fraction we need.
Our fractions have to look like this:
I don't think this is possible by changing the opentype settings.
