[help] How to change the interval of many timers using a loop

Hi i want to change the interval of many timers using a loop.The first idea that didn't work was something like that:

dim time(5)
dim num(5)
dim i =0


time(0)=timer1.interval
time(1)=timer2.interval
time(2)=timer3.interval
time(3)=timer4.interval
time(4)=timer5.interval

num(0)=5
num(1)=16
num(2)=12
num(3)=33
num(4)=40

for i=0 to i=5
time(i)=num(i)
next

Sorry if this question is stupid but i am new in vb lang
