Problem in displaying total amount in report

Hi All

Please find attached the workbook.I have a problem with the Report.The report doesn't display the total amount correctly. In the MI reports,click on daily MI and then click on Find total cheques and total amount and then press generate report button. Now for each bank the number of cheques comes up fine but the total amount for each bank doesn't display the correct value.
I think it concatenates the text together and doesn't sum up all the values.

I hope anyone can figure it out please.

Thanks
