having two OnLoad event handler

I am having trouble having two onload event handlers in the body tag.
for example:

i would also like to run:
OnLoad="tickinit()"
within the same body tag. I can only seem to get the first one that is typed in to run. it doesn't cause any errors but the second one just won't run althought the colors and sizes all do react as they should.
How do i put two onload event handlers into one page?
Thanks to all who can help.
