Position Converter "Chr" error suggestion

[jtdendunnen]

using ChrX in the Position Converter (instead of chr) gives:
"Expected W:(0123...) (at char 4), (line:1, col:5)"
I do not understand this error, pointing to the X while the problem is the 'C'.
Using Chr1 gives:
"Accession number Chr1 could not be found in our database or is not suitable for the requested conversion". In a sense correct but not really helpful. I suggest to automatically use 'chr' when people give 'Chr' yet warn them the description was corrected.
