I love this forum because I always get an answer quickly and it always helps! Here's an easy one. I need a formula that will give me a negative number in column c when column a is a positive and column b is N/A. Column a represents orders, column b represents inventory and column c is supposed to be inventory after orders are filled, and when there is no inventory I need it to reflect a negative number. The formula in the example is what I have in there now. Sorry for my ignorance!
A.....................B.........................C
Orders.........Inventory.............Net Inventory
100................N/A.....................=A3-B3
A.....................B.........................C
Orders.........Inventory.............Net Inventory
100................N/A.....................=A3-B3
