try using VCE
I was about to suggest using VCE.
If your making a timer, you dont need to use variables.
If the timer is counting up, have these events to count in minutes:
with four print bricks named m00 m0 : s00 s0
thats what i use, to keep track of the ten's digitAlso. have a brick evented to incriment s0's print count each second.
s0- on printcount overflow, s00 incriment printcount 1
on printcount overflow, s00 ifvalue <var:brick:printcount> = = 6
s00- onvariabletrue, self set print count 0
onvariabletrue, m0 incriment print count 1
m0- onprintcountoverflow, m00 incrimentprintcount 1
If yur building a timer that counts down, its far simpler.
Just change the relay to decriment s0, set s0 do decrement s00 when it underflows. event s00 with
onprintcountunderflow, self set print count 5
