unique input mask

[garret]

Hello. I am trying to create an input mask for a field which will
always look like this:

Letter-#####

except the letter will always be either A, B, C, or D. I know how to
limit it to a letter but not to only these letters.
Thanks.

Set the Validation Rule for this control to:
Left([ControlName],1) In ("A","B","C","D")

Also set a user friendly Validation Text message.

Wondering...can you explain what this code does?

Also, it doesn't work for me. What is the ControlName? This is in the
creation of a new field in a table..not a text box in a form.

Please always include the relevant portion of any previous post when
asking a question. Someone reading this last post will have no idea of
what you are talking about.

1) You should place the
Left([ControlName],1) In ("A","B","C","D")
directly in the Table field's Validation Rule property.
Since no one knows (except you) what the real name of the field is,
[ControlName] is generic and should be replaced by you with the actual
name of the field.

2) You should not be doing any data entry directly into a table.
Always use a Form.

Hey Fred, sorry..

I tried entering
Left([ControlName],1) In ("A","B","C","D")
substituting the "ControlName" with the field name (DrawingNo). This
however gave me several error messages, so I am still confused.

I know I would be entering data on the form, but I didn't want to make
the validation property part of the text box (as I thought you thought
I was trying to do), I wanted it to be a property of the field.

Shall I guess what the error numbers/messages are?
Probably that you can't enter a letter in a field that is designated
as Number datatype.

If DrawingNo is a Number datatype, you can NOT enter any letter in the
field, period!
If the DrawingNo is Text datatype, then perhaps you can let us know
what the error messages are.
I assume your dataentry is something like "A2345", "C9876", etc.
If you place
Left([DrawingNo],1) In ("A","B","C","D")
in the field Validation rule property, it should work (if the field is
Text datatype). It works for me.

Use a form for data entry, always. After you add the validation rule
to the table field, add the field to the form, using the field List
tool button.

After Inserting that code into the Validation rule property, I get the
error message

There was an error compiling this function.
The Visual Basic module contains a syntax error.
Check the code, and then recompile it.

Does this have something to do with any properties in Visual Basic that
may have been changed?

Nevermind, it had something to do with my previous data and my
unfinished module, but I cleaned it up and it works correctly now.
Much thanks for you and your patience =).
