Don't top post!

ISNUMERIC probably doesn't work because it tests the data type,
not contents. What you enter in a text box is necessarily text.

So either

1) Try and convert the text to a numeric value using STR2INT,
   STR2NUM or SSCANF and test if the conversion was successful.
2) Use a regular expression first and check if the entered text
   contains a valid number.
