Dear VoG and AD Taylor
Many thanks for your prompt replies.
Followed your instructions,VoG, all now fixed. The "Fixed decimal place" box was showing
-2 (minus 2). Presuably the minus sign multiplies the input number by 10, 100 etc depending on the number following the minus sign,as against showing the number in a decimal format with the "point". Interesting.
Thank you both again.
