Robert,
I don't think that's it.
With your version of the formula one hour "is worth" as much as one minute. Try it out with 1h 0min, then try it again with 0h 1min - if I'm not mistaken you'll get the same result.

Not that *I* see any real problem with the original formula but you could try:
Code:
blue_delay_in VAR WORD
blue_delay_in = (fadesetHR[0] * 3600 + fadesetMN[0] * 60) / 255
/Henrik.
