Tnx!When i use the code for more than one field i get an error.Adobe will give an error for all field before i can type new info in the field.

I know what the problem is. When i use a dot instead of a comma in the prices the function will work.Strange is that the total will be display the price as 2,50Do you think it is possible to use the prices as well with a comma instead of an dot? This is the standard in the Netherlands.
