My problem is this
The item sales staff also manually calculate how many items and what the total cost of all items sold is over a day. To do this, they itemize each item on paper and add up the total number of items. They check through the file to check through the to check the totals of each item, write all these down on a paper ledger and manually add all the totals up to calculate the totals sales. They would like an interface with one calculation button and one label or text box for out put. This leads the user down a very rigid path where inputs are only allowed via an input box. The calculation button will invoke a input box which successively asks for enter a product price, to stop, enter a negative number or press cancel the title of the box will be enter price for item number x (where x = either number 1 or number 2 etc) when a negative number or the cancel button is pressed a second input box will appear. This states enter the quantity sold for the item priced at x pounds (where x = the price of the item entered by the user in the first input box). The title of this input box will simply be enter quantity if the user does not enter a quantity and tries to escape from this second input box, a message will appear stating quantity sold must been entered as a positive number
Tip to do this a do loop with a nested do loop must be used
I am completelky lost with the input boxes only taking the informtion in
can anyone help me with this?
