When I try and use ToHexString() on a variable, It crashes with "Member function not found in BrightScript Component or interface."

Simple use such as

fadelevel = 255
print fadelevel.ToHexString()

Am I using it wrong?

ToHexString() is an roByteArray method, not an integer method.

Is there no way to convert a int or a string to a hex value? I have to do it from an array? cause I only have one value to convert, not an array of values. Unless I'm misunderstanding.

I think you're confusing roArray with roByteArray. You can create a roByteArray from an ASCII string, then call ToHexString() on it. http://sdkdocs.roku.com/display/sdkdoc/roByteArray

Just for those who look for further ..

print StrI(255, 16) '= "ff"

Umm... please don't do #2.
That function is not written efficiently, plus as the author notes in comment - there is a better way.
