You guys really should look at the module guide first...
Does "AutoDepositUpdate" ring any bell?
Anyway, Erik, you have to see the code as LEGO blocks. You get a number of blocks that you can recombine, but you can not make any new ones, nor can you switch parts among those "tags".
What you want doesn't resemble in any way with modules that can be found in the game. so it can't be done. The game had no modules that relate a "field" with increase of income.
However, not all is lost...

in ZH "AutoDepositUpdate" has an additional option to give a boost through an upgrade. If you can grant yourselves an upgrade, you can also get a bonusfactor...
