Hello everyone.  I am trying to sort some alphanumeric values.  For the strings that are alphanumeric, the letters will ALWAYS be in the first or first and second positions in each string.  For instance, D201987 and MP3928473.  The rest of the strings, which have varying lengths, contain only numbers.  Because the strings are not stored as numbers, however, I had to convert them.  So here is my code thus far.

If NumericText({TLORDER.BILL_NUMBER}[1 to 2])
    Then ToNumber({TLORDER.BILL_NUMBER})
Else {TLORDER.BILL_NUMBER}

However, I keep getting the error message that a number is required in place of {TLORDER.BILL_NUMBER} in the final line.

Ultimately my goal is a list that has the data sorted by numbers only strings (smallest to highest), then by the strings that begin with one letter, finally by the strings that begin with two letters.

Any help would be greatly appreciated.

Your code worked great!  Thanks a million.
