how to transfer result from 1-st formula to 2-nd formula?

Hi

i just wrote application with 2 formulas in it.

1-st formula is too complex&long and uses "if-thenif-then" calculations.

how can i result from 1-st formula (numeric value) supply to calculations of 2-nd formula in same application?

thank you!
