Always use QUOTE and CODE bbcodes when pasting error messages and codes.

Well, evidently, the str_repeat function requires the second argument to be of integer value above 0. The 'iif' statement isn't natively supported in PHP (nor in many other languages) as far as I know, so I'm assuming it's user-defined within one of your scripts; but a quick bit of research indicates that it operates on the basis of 'iif(condition,true,false)' meaning that it is evaluating '$navlinks['level'] - 1' if '$navlinks['level']' is any different to 1 - such as if it is 0, meaning that '$navlinks['level'] - 1' obviously become less than 0 and therefore illegal in that context. Additionally, I would recommend simply using 'condition ? true : false' as it is natively supported by both PHP and a wider range of languages, and much more likely to be recognised and understood by more people.

This is what i found about str_repeat():

string str_repeat ( string input, int multiplier )

Gives multiplier repeats of input_str. multiplier has to be greater or equal to 0. If multiplier is 0, this fuction will return an empty string.

(Sorry for the possibly bad English, but I had to translate this from Dutch.)

Basically, you are getting this error because $navlinks['level'] = 0 since subtracting 1 creates a negative number. Try displaying $navlinks['level'] prior to your condition so that you know its value because this will help in debugging the error. If that isnt it, then i dont know what the problem could be.
