I'm not sure that I understand your question. When you say " I want to
restrict values to uppercase letters from A-B inclusive" aren't you saying
you want to restrict values to A or B? Also, are you trying to restrict the
data being entered into the text box or the data in the underlying recordset
that is displayed in a bound textbox?

When using > and < with characters, it is best to convert the character to
its ASCI equivalent so >= "A" becomes >=ASC("A")

Subject: [ms_access] validation rule for text box

Text Box properties-
validation rule-
I want to restrict values to uppercase letters from
A-B inclusive in TextBox1
I want to restrict values in another Text Box,
TextBox2, depending on the letter 
entered in TextBox1
I tried using the Expression Builder to come up with
the following rule for 

TextBox1:

=[txt]>="A" And [txt]<="B"

but everything I enter, A, B, Z, a, b, etc. fails the
validation test. I can't get to the second test until
I get the first to work. I tried setting the
validation rule in both the form and the table but
neither worked. Can someone please help?

Thanks,
Mark Espinosa
