Hello i have a problem doing a iteration in my model:

The Model adds a field(called Leistung) in an attributetable and then calculates the value for this field. Afterwards i make a Ascii File(could also be another filetype) to save the Table with the added field. This calculated value is the Energy produced of a Photovoltaic Panel in one hour. Since i need to do this for more hours (and days and years) i want to have one file at the end where i have all the calculated values saved (and not one file for every hour). i dont know how to do this, can somebody help me or give me a hint?

in the picture i posted my model and the calculatfield statement.

btw. Im using ArcGis 9.3.

thanks in advance for your help

you'll always have only one field in your shapefile (called Leistung) to calculate this values, but in a lot of shapefiles... Is that right?

I think you should explain better what you want...
