okie. am creating this form which requires someone to key in name and figures. to prevent people from keying in alphabets as figures, i used the "isnumber" function to allow the cell to read "true/false"
what i like to have is that:
when the cell reads "false", the button will read as "ERROR" and is unclickable
when the cell reads "true", the button will read "OK" and is clickable, meaning the data will be written.
am a noob in this, kindly pls help in layman terms! really appreciate a lot!!
