minor changes to spreadhseet

i need a few changes made to the attached spreadhseet: the combo in cell E15 has been made by a coder. it takes the number of bends in a panel (cell D15) and creates a number of lengths (no. of bends+1) in the combo. these can then be entered, with the total appearing at the top. 1 - i would like this combo ammended so that it only becomes visible when the user chooses the no. of bends in cell D15. 2 - i would also like it to not say '# items' before any of the lengths have been inputted, but to say 'Enter Lengths' - or 'Enter Heights' for the combos in column G 3 - i then want this to be in use in every other place where i have pasted a currently non-working combo. the only difference is that these should take the bends value in the cell to to the left of each combo. again, each combo should only become visible when a selection has been made in this 'bends' cell to its left. 4 - the only other difference is that each combo in column G should ask for a 'Height', not a 'Length'. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
