How do I change my weight loss on my profile ???

You are going to need to go through the site for the weight loss trackers to do that-the same place that you created your tracker through.

OR, instead of making a whole new tracker each time, just go to your User CP, then choose "Edit Signature" from the menu on the left. Then you can see the full HTML code for your signature. Within the codes, just find what your current weight was (in your case, the 218) and change that number to your new current weight.

If you see the images instead of the HTML code when you go to edit it, then you must first go to "Edit Options" and scroll to the last option (Miscellaneous Options) and change it from "Enhanced Interface" to either of the other choices, then go back to "Edit Signature," and the HTML codes should be there. Hope that makes sense
