This will not work the way you think it will ...You have to remember that the [lastrandom] and [random] tags are relative to the thread they are called in, they have no connection with any other threads. Therefore, the same [random] and [lastrandom] values could theoretically be created at the exact same time in two or more completely separate threads.The most reliable and 'practical' way to create a unique SKU value across *all* active webcat threads is by using the [cart] tag. That's why WebCat's internal [cart] calculation code uses date, time *AND* a special 'index' value that's never used in two different threads to generate a guaranteed-unique [cart] value every time.If your goal is to create a unique SKU value that *also* has some code to indicate size, color, etc. the best solution is to use something like this:[cart][size][color][etc]Where the size, color, etc. values are simply *appended* to the end of the guaranteed-unique [cart] value.Sincerely, Ken Grome
