水晶报表获取总和错误

Question

I watched video tutorial about Crystal Reports. I am confused because when I click Insert > Summary the Sum , Average and etc. are not on the list of Calculate this summary

I tried to search web but no luck. Please help me fixing this.

Answer 1

That would be because Crystal sees this field as a STRING and can't sum a string. You can write a formula field that will convert a string to a numeric and then do a summary of the formula:

Val ({YourTable.total})

Answer 2

@Icebergman_NewProgrammer, Your Sum field is a nvarcha/nchar or others.

plz check this and insure this int/decimal/numeric etc.
