asking for number?

Not so sure that I am supposed to put the full number from the gas meter in the sending a reading grid as it keeps asking me to submit a number and I already put the reading in. Didn’t used to have this problem with Scottish Power’s website submitting. What do I input?
Also never used to have to submit the tenths dial on electric but this site asks for a number after a point which can only be the red dial on my electric meter?

Just put a zero after the point.
