ZITI Caterer

When I click generate Quotation, It just hangs. Please fix it

Hello guys I give you 5 start for taking a step ahead and making app for this kind of business which was must needed for catering business I like the app but they are many basic issues which you guys can fix like when I write any name of the item which I want to add in the menu and by mistake I wrote the spelling wrong it doesn't correct by it self and I can also not correct so add that option to change the name or delete the name and add new one I want to write more but no space but great app.
