Problem in Validating txtfield

[madhuriks]

hi,
i had done validation in my project...my prob. is if i enter 'AM98' in txtfield it is taking....but it should not take..it has to take 'MA98'...here with i m sending the code...can anyone suggest the solution..its urgent

chkAct=/^[MA]{2}\d{2}$/;
if (chkAct.test(form.act.value))
{}
else
{
alert('Invalid \"Activation Status\" Entry');
return false;
}

Thanks in advance,
madhu.

but you specified the letter portion to be: AM, MA, AA, MM. [MA]{2} means "two times a letter out of M or A" (keyword: character class)

if you want MA exclusively, use

/^MA\d{2}$/
