Something like this: ^^0-9]{1,3}(?:..0-9]{1,3})?$

Hi @DMojo,

This may also work (The user has to enter the comma though or else it reads as a whole number):
 

Kind Regards

Hi @DMojo,

Putting a “.” in the middle may work:

^>0-9]{3}.(.30-9]{3})?$
It will accept a value like “123.” and probably read the decimals as null but it doeds not allow 3 decimals for some odd reason

Kind Regards

Thanks so much for the input guys!!! 

Using 

^[0-9]{3}.(.[0-9]{3})?$

I get the result below:

(If the user enters 123123 into the field)

I need the result to be 123.123

So the user can enter up to 6 numbers, 3 before 3 after the decimal.

I appreciate the help so far.  Please let me know if you think of anything else that might work.

Kind Regards!

Hi @DMojo,

This expression works better as it validates 3 didgits after a comma:

^[0-9]{3}.(?:[0-9]{3})?$

Im still not sure how to convert a number to a decimal with the expression so it wont work with a integer.

Kind Regards
