Hello All!!

I have created a small VB program in excel to calculate a number based on about 5-6 given numerical inputs. This program also uses IF...Then....ElseIf logic by taking some of the inputs and based on the values, routing the inputs to different equation sets for calculation. Anyway, I have setup two ways for Excel to calculate the correct output: one, is by pushing a button that prompts each numeric input in an application box and second, by inputting the values into the correct cells manually and then clicking on the output text box (the code is based off of the "GotFocus" feature for the textbox). However, here is the problem!! When the user inputs using the button method everything works fine. However, when inputting using the manual method into each cell and then clicking on the textbox, the screen starts to rapidly blink over and over again and will not stop until the user clicks somewhere else on the screen. The program then spits out the value into the textbox. The answer is right but this is dreadfully annoying. DOES ANYONE KNOW HOW TO KEEP THIS BLINKING FROM HAPPENING?
