Answer 1

Make a function called TotalList which will return a double data type.

In this function declare a string, integer and double datatypes. The integer value will be used in a for next statement which will loop through values from zero to List.count -1)

Using the for/next integer value index through each listbox member using the selected property and read the selected text property into a string variable.

Using the Val() function convert the string variable into a double data type then totalize this converted value into another double data type called "total"

Upon exiting the loop return the "total" variable

Call this function after loading the list box and assign the returned value to a text box.

mtTextbox.text = TotalList
