John Tiller Campaign Series Editor glitch

[CelerEtAudax]

I have just made two Eastfront scenarios using the editor.  Unfortunately, I have hit a big problem in setting the number of turns.  When the dialog box comes up, the default value is 30, written thus: 1-30(d)  This is not the default value of 10 mentioned in the manual, but It shouldn't have been a  problem.  I entered a lower value as follows: 1-16(d)  When I hit the OK button, a box popped up with the following.  In the top left corner was written 'invalid input'  In the centre was a yellow triangle with an exclamation mark.  Next to that was the message 'invalid turn value(s)


I have tried entering different figures, via the main keyboard and the numbers keypad.  I have even experimented with upper and lower case and the space bar but nothing has worked.  The only number the editor will accept is the original figure of 30.


Can anybody help?


Thanks in advance,
