validate a field with error message

[webandwe]

Hi

here is one of my fields:

[HTML]<input name="a2" type="text" id="a2" onblur="MM_vali dateForm('a2',' ','R');return document.MM_ret urnValue" />
[/HTML]
If I do not fill it in it says a2 required, I need to keep a2 but want to write my own error message? (name is required) I need to change a2 to name..

I am working with a mysql database and cannot change a2 to name.

How do I it?

Thanks
