Solution #1:

Insert debugging into HTML

C = 'L'
-- lots of stuff here…
Say 'C='c
Say 'The time is' time(C)

Result:

C=L The time is 13:43:28.484793

Problems:

  1. The debugging affects the structure of the webpage
  2. You might not find it easily in a complex page
  3. If the data contains an "<" then it will be interpreted as HTML
  4. Once you've found the problem you have to take the debugging out
