Very good.
After more testing I find the two wrapper approaches actually don't work every time. Lockscreen didn't work for me at all and the second worked intermittently.
The function is called from a command button on a page of the pageframe. The text boxes being checked reside on other pages.
The refresh() command in the activate of the page being returned to seems to work every time.
Thanks again,
