How about this?

Frame 1



// function for searching through string
function parseString (testString, searchItem) {
for (i=0; i<testString.length; i++) {
// check for first letter
found = &quot;&quot;;
if (searchItem.charAt(0) == testString.charAt(i)) {
// if first letter is found search for substring
for (j=0; j<searchItem.length; j++) {
if (searchItem.charAt(j) == testString.charAt(i+j)) {
found += testString.charAt(i+j);
// if complete match is found return result
if (found == searchItem) {
return found;
}
}
}
}
}
// if no match is found
found = &quot;Search item not found.&quot;;
return found;
}

Frame 2

//
//initialise variables for your example
//
text = &quot;milk;chocolate; and coffee;&quot;;
testString = new String(text);
find = &quot;chocolate;&quot;;
searchItem = new String(find);
//
//go find your example
//

result=parseString(testString,searchItem);
trace(result);
stop();
