I have an issue withe the field calculator. It is impossible for me to multiplicate 2 columns (area * KZ). The result is always "0". I used the formula area * KZ....is this the right formula? LINK to shape file Here the steps I did:
- Using the "advanced python field calculator" to replace the strings "A"into 1, "B" into 2, "C" into 3 and so on
- Using the field calculator (processing plugin) with the formula KZ * area without success
