Date Calculation without error without / between dates

[PerivanP]

Hi,

I have manged to find a javascript that does the date calculation which worked with the date typed as 29/12/1961, now the customer want the date just typed as 29121961 in a text filed set to comb 8 characters now the calculation doesn't work, I've tried removing the / from this line of the javascript
dob = util.scand("dd/mm/yyyy", dobValue); but still no luck.

I've attached 2 test PDFs number 1 works ok number 2 doesn't, and also the working javascript below.

Unfortunately I do not have the skill to work this out and hopefully someone else will if at all possible

Thanks in advance  

Paul

Javascript used below

dobValue = getField("DOB").value; if (dobValue!="") { dob = util.scand("dd/mm/yyyy", dobValue); var nTimeDiff = (new Date()).getTime() - dob.getTime(); var nYears = nTimeDiff/(365*24*60*60*1000); event.value = nYears; }

Use:

var dobValue = getField("DOB").valueAsString;

Use:

util.scand("ddmmyyyy", dobValue)

I just get the javascript debugger console with all these errors

Change the first line to:

var dobValue = getField("DOB").valueAsString;
