Hi Simon -

A "not equal" sign is !=. So something like

if firstname != "Kou" then 1 end

For checkboxes, just to be sure you are talking about a "Yes/No" field set to checkbox? If so, then are evaluated as either  "= true" or "!=true". So for a display only you can do:

checkboxFieldname = true

I hope this helps.

Hi Simon

Not equal is !=

Checkboxes use the 'Yes / No' field type. If we have one called Checkbox then

Checkbox

Results in "Yes" or "No"

number( Checkbox )

Results in 1 or 0

But you don't need to check for these values in your code, this works OK

if Checkbox then
    a := a + 1
else
    a:= a - 1
end

Hope that helps

Regards John

stating "not" also works

ie...  if not(DispFlag) then 1
