Heya, Xiu. Welcome to TSDN!

Where do you define $menuid? It seems as though your script keeps running the exact same query every iteration.

I have a question that I'm hoping someone here can answer. Let's say I have two fields which have a beginning number and an ending number. What I'd like to do is have Access generate a list of numbers between the beginning number and the ending number (inclusive) for each row that exists in my start table. For example, my start table might look like: Begin End 513525 513528 513530 513538

Hey guys, I'm new here, just a simple question. I'm learning to Program in C, and I was recommended a book called, "Mastering C Pointers", just asking if any of you have read it, and if it's worth the $25USD. I'm just looking for a book on Pointers, because from what I've read it's one of the toughest topics to understand. thanks in advanced.

I'm new so i apologize if this is in the wrong spot. I'm also new to programming in C and i've been searching for quite a while on how to create a program using C that will generate two random numbers, multiply them, and ask you for the result.
