Your way would work perfect except that I simplified the function I posted, for illustrative purposes -- a mistake, I realize. The returned error message is actually composed of an imploded array, whose contents are entirely dependent on the code in the function (basically it varies depending on circumstances, so I can't write a test for it). I ended up just performing the checks in the script itself, rather than in a function, because I was only using a function as a subroutine to keep my script's switch() statement nice and clean. But in this case, it just was too much trouble (I was also running into a situation where I had to deal with a global variable, etc). Since I don't really need this anywhere else in the script, I don't really even need it to be a function. Thanks for your input though, Julio. Erik ---- Erik Price Web Developer Temp Media Lab, H.H.
