Thank you for responding.
I don't know how it happened, but yesterday I discovered that my tracker at
www.medhelp.org was no longer displaying my weight - just my BMI. That was why I could not enter my weight either at Medhelp or on my remote site.
Once I went into my settings and put my weight back into the tracker for display, I was back up and running.
Not sure what happened behind the scenes at Medhelp to change my settings but I am OK now.
Thanks
