Short answer question with a number range that doesn't just have whole numbers

Sue.S.4

This is a similar query to one I have posted, but even with the short answer strings I copied over, answers are still being marked incorrect. So I might extend my query (and include the initial one) now I have more information:

How do we input an answer in a short answer question which permits any number between a range - eg any number between 1000-1400. We have [1000-1400].

I also have a number range between 5-12.

Questions are being marked wrong, because students may put one of two things:

A decimal number - eg 9.5…. or they also put the unit of measurement (micro millimetres … in a few different spellings).

The quiz has already run now, but it would be good to fix in the Master site for future delivery.

Thanks in advance.
