Budgeting

I wonder if there ever existed a budget form in AIESEC Croatia where if one line is added/changed, the whole table formulae won't crash?

For my own problems I decided to add line for better transparency: AI fee and LC visits costs, so what do I have in the end - 2 days of creating new sums in budget excel table... all these crashing formulae make me mad up to swearing hard.

This excel sheeeeeeet is absolutely non-linguist friendly.
