Form validation

[Guest_imported]

Hello,

I am trying to validate a form to make certain that any number input is in increments 1000. You knonw, no less then 1000 but must be 1000,2000,3000,4000 and so on.

Can somebody help me with this

example
a=9000 % 1000;

a will then = 0. If it is anything else then it is not an increment of 1000;

if (parseInt(myForm.myField.value) % 1000 != 0 ) {
alert("Form value is not a multiple of 1000"
return false;
} Mise Le Meas,

Mighty

You might want to add a myForm.myField.focus() to Mighty's function, just for extra functionality! "The surest sign that intelligent life exists elsewhere in the universe is that it has never tried to contact us"
