Ken, I think you need to make it like this:

   if not matchText(p1,"^[A-Pa-p]$") then exit to top


Otherwise it will match strings that contain the target character,  
which I don't think is what Sarah wants.

e.g. 123B will pass the test.

So for the other examples

   if not matchText(p2,"^[1-8]$") then exit to top
   if not matchText(p3,"^[SD]$") then exit to top  -- note s,d won't  
match
   if not matchText(p3,"(?i)^[SD]$") then exit to top  -- matches SDsd
   if not matchText(p3,"^[SDsd]$") then exit to top  -- matches SDsd
