That's great. Mind sharing the solution so others with the same issue can learn from it?

yes i have update the code in the first page to be used

so what do u suggest?

Before, you should have left the post alone. Now, you should put the post back the way that it was.

Then, you should post a reply with the updated code that solved your problem.
