Help:VE1
From TrainzOnline
The tag tagname in container containername is not a valid Decimal value.
The value specified for the tag was not a valid decimal number.
For example, the config.txt file for a traincar included the tag line:
mass 86,900
which created the error message:
- VE42: The tag 'mass' in container 'traincar' is not a valid Decimal value.
The correction is to change the tag value in config.txt so that it is a valid decimal number.
mass 86900
A valid decimal number consists of an optional minus sign, one or more digits, an optional decimal point and additional digits.
