Populate array with user inputs

[jbwethington]

I am trying to populate two arrays. One with combo box and the other with a text input. The combo box has multiple choices of different counties people live in. The text input is for income amount of person that lives in each county. I will later need to break info into Average Household income and Number of House Holds surveyed.

Data will look like the following example:
Average Households Income
Ohio: $30,000.00
Hamilton: 40,000.00
Butler: 20,000.00
Clermont: 30,000.00
Warren: 30,000.00
Kentucky: 35,000.00
Boone: 40,000.00
Campbell: 30,000.00
Kenton: 35,000.00

I will use data loaded into array to figure average income for each state. and then total for each county.

I will also need to get the following data:
Number of HouseHolds Surveyed
Ohio: 5
Hamilton: 2
Butler: 1
Clermont: 1
Warren: 1
Kentucky: 5
Boone: 2
Campbell: 2
Kenton: 1

I will load the array with a button click, each time button is clicked input fields reset and input second set of data for array and that continues. Once I have households data entered I can click another button that will show Average Household Income and then a third button to show Number of households surveyed. I will display each in a message box when button is clicked. Right now I need help loading array. I know how to set arrays up and how to hardcode data into the array, but I have no idea how to make inputs go into an array. I have code started if you would like to see.

Thanks for any help you can give.
