Me and my groupmates want to create a program, wherein you input numbers expressed in words like "nine hundred ninety thousand one hundred and fifty" into numerical units like "990,100.50" including the decimals. and wherein a message will show up indicating an error in the input words if ever the users will try to put other words aside from numbered words. We started making this code all day but can't seem to make it work efficiently.

this is the whole code that we made, we would really appreciate some comments, help or guidance. We are currently just beginners in programming and mostly rely on books only, because our professor hasn't taught us that much yet. thanks!
