Hi,

I am designing a form where I have some textboxes where I
want the user to enter numeric value (with or without
decimals).

since the textbox does not have properties to restrict
input data to only valid numbers, how do I do the
following:

(a) efficiently ensure that the data entered is a valid
number
(b) save the entered value (which is in text format) to a
spreadsheet cell in the format of a number

TIA
