Hi Charles,
Write an additional command that checks the contents of all fields.
For example:
funtion checkFields
repeat with x = 1 to number of fields of grp 1
if fld x of grp 1 is not a number or fld x of grp 1 < 0 or fld x
of grp 1 > 10 then
return false
end if
end repeat
return true
end checkFields
Now, when the user uses tab or return to navigate to another field,
make the closeField handler call the function.
on closeField
if not checkFields() then
set the text of the target to empty
select text of the target
else
pass closeField
end if
and in the calculate button, use something like this:
on mouseUp
if checkFields() then
-- calculate and go next cd
else
select text of fld 1 of grp 1
end if
end mouseUp
Naturally, you could add a few answer dialogs with warnings and a few
system beeps, but I wanted to keep these examples simple.
I hope this helps.
Best,
Mark

I have entry fields that the user fills in with numbers by using
the tab, return or enter keys. Each field is checked for a range of
scores by catching the exit or close field. If the user enters a
number that is above the range for the entry field, a dialog box
appears warning them of the mistake and puts the focus back on the
field. Here is my question: I found that if the user uses the tab,
return or enter keys to enter the data with fields and then goes
back using the cursor and changes a data entry that is above above
the range and instead of using the above keys then uses the mouse
to click a Calculate button which computes the scores and goes to
the next card, the error box does not appear but I get an execution
error in the standalone. How do you trap for this when the user
does not use the tab, enter or return keys but uses the mouse to
move the cursor to click on the calculate button?
