Error 20: Unable to understand the sample number format

MEGS_Log can understand sample numbers in the [A]B[C], where C is an optional sequence of letters that make up the sample prefix, B is a required number (digits only) and A is an optional sample prefix that can contain letters and digits (there must be a letter separating the digits in B from any digits in A).

MEGS_Log may give this error if it comes across a sample number that does not meet this format when carrying out some sample number actions (such as relabelling).

Either change the format of the sample numbers in use to something that MEGS_Log can recognise, or avoid using the Relabel Sample Number command (you can still edit each sample number individually with the Sample Number command on the borehole popup menu).
