How do I show 2 digits for a Global number, when its '00'

I made a simple clock in a game I'm working on. Each action has a time it takes to complete, that's added to "TimeinMin". When "TimeinMin" is greater then or equal to 60, I add 1 to "TimeinHR" and subtract 60 from "TimeinMin"

My issue is getting "TimeinMin" to read '00' When needed. I end up with times such as 4:0 instead of 4:00

I'm new to Construct 2, came from Stencyl which was frustrating me, so theres a bit of a learning curve here. Thanks in advance.

From the manual

zeropad(number, digits)

Pad number out to a certain number of digits by adding zeroes in front of the number, then returning the result as a string. For example, zeropad(45, 5) returns the string "00045".

Dang it! I knew it would be something simple, but I didn't see that while I was searching around, thank you very much for the fast response.
