Control data entry formats

Hello,

I need tto control data entry in a Excel workbook but I still can not find any solution to this problem.

I have a column "A" where the users need to fill out with ID numbers, but the ID numbers must be only from 1 to 99 or the word "Out", in some cases the ID correspond to a period and in this situations the first digit and the last digit need to be separate with a "-" (example: 1-20 or 92-99),

I attached the file with the example.

Any suggestions would be greatly appreciated!
Thank you in advanced.

One way, using this as the Data Validation formula (applied to yellow cells):

=(OR(IFERROR(AND(ISNUMBER(--A2),--A2<100,--A2<>0),FALSE),IFERROR(A2="Out",FALSE),IFERROR(AND(--LEFT(A2,SEARCH("-",A2)-1)<100,--RIGHT(A2,SEARCH("-",A2)-1)<100),FALSE))=TRUE)

You're welcome and thanks for the rep.
