Actually I have to show result as OK when the user enter value as infinity ...if the user's input value is not infinity then result should be displayed as NOT OK by comparing the user's input with reference value.
naming conventions can help... so where exactly on your screen is that Textbox1?
I can see 6 textboxes in your screen...
probably it makes sense to rename it to something more useful?
