Datepicker issues

[Qliksense7]

My dataset has the Date format as 'M/D/YYYY hh:mm:ss TT'. I need to obtain a Date picker with the date field in the format mentioned
I changed the script in the data load editor to this format mentioned loaded the data and also created a new dimension with  date format mentioned above. I'm still not able to get any parameters in the date field to move forward 
I'm still facing the error "Invalid Dimension". Is there any way to obtain a date range with the mentioned format?

Thanks for the help

I had a similar issue. My data set format was 'M/D/YYYY h:mm TT'. 

In the data load, I changed the TimestampFormat to match the data and used Timestamp on my field. 

//SET TimestampFormat='M/D/YYYY h:mm:ss[.fff] TT';
SET TimestampFormat='M/D/YYYY h:mm TT';

Timestamp([DateField])

In the DatePicker, use Language and Labels > Format to display as needed.
