Excel-Limit Size of Four Fields

Excel-Limit Size of Four Fields

(OP)
Using data validation, I am limiting the number of characters which can be entered into various columns. However, I have four columns, each of which need to be able to take 400 characters, but be limited to a total of 400 characters for the four columns. (They are being concatenated and then loaded into a VARCHAR(400) field in SQL Server). Is there any way to do this without using a macro? I have tried adding another column with the sum of the characters for the four columns and then applying the data validation to that column, but it doesn't work in a satisfactory manner. Can this be done without programming?

Hi,

YES!

Use a Custom Data Validation formula.

Assuming that the 4 columns are A:D in row 2, the DV formula in each column is...

=LEN($A2&$B2&$C2&$D2) <= 400

Ta-DAH! Works very nicely. Thank you.

OOPS!

While running the last test before sending this out into the field, I found that if any of the fields is empty, the validation rule doesn't see the problem. This is what has been coming in from the field; the entire address is in the first of the four fields and the rest are blank.
For the purpose of determining the length of the four fields, it's kinda like concatenating a null into a string in T-SQL.

in the DV > Settings tab...
