I'm moving my very first steps in Zoho Creator.

I'm a little bit confused, but still going on...

My question is this:

I'm building up a simple application to manage rally stages time for a game.

At this moment i'm going pretty good on Excel but I would like to go better...

I'm using in excel a text format for record stages in this format mm:ss.ms0 (minutes 2 digits, seconds, 2 digits, milliseconds 3 digits) and converting them in milliseconds for calculation.

I'm seekin' in Zoho a way to format text field to obtain a correct input XX:XX.XXX but probably i'm so dumb that i cannot find the way... 

Many thanks for any advice/support.
