Script that requires the user to type in "Y" or "N".

[SandiRR]

I am working in Acrobat Pro X1. and am designing a fillable form that has a column that requires the user to put either a "Y" or "N" only. (This may be changed to "P" or "F" pass or fail). I made an Arbitrary Mask with "A" and this works except that any alpha can be typed into the column. I know that this should be simple but I'm just not finding it.

Do I need to run a validation?  and if I do, what would that look like?

I would appreciate any help.

Thanks!

Why not use a drop-down field, instead?

Normally that would work but there is only enough room for one character in the column. (Basically the drop-down is too big) Also, there are 28 lines in the column with text boxes on either side.

OK, then you can use this code as the field's custom validation script:

if (event.value) event.rc = (event.value=="Y" || event.value=="N");

Perfect! Thank you!
