Hi,

    On the home page of my website i have a simple report running against a UDT using the filter. It takes the users from a table of sales figures and returns any that have a total of over 17000.00. It was working absolutely fine I have not changed it and suddenly im getting the following error and i dont know why.


A critical error has occurred.
Cannot perform '>=' operation on System.String and System.Decimal.


My filter statement is simply

Total >= 17000.00

 

 

Any help would be sooo appreciated, im nearing my deadline and this has come out of nowhere!

Thanks Sam

First off, I apologise for the delay in responding. I hope your deadline hasn't passed (or that you have fixed your problem).

If the UDT column you are using has a data type of "Decimal", you may need to convert the value in your filter using the Convert function (I'll post a link below to the formatting details for this field). If the UDT column has a data type of "Text", you'll need to convert the field to Decimal (since a Text comparison would not have the effect you want), again this is done using the Convert function.

The format of this string is the same as the one expected by the Expression property of the System.Data.DataColumn class. More details on the format can be found here: http://msdn2.microsoft.com/en-us/library/system.data.datacolumn.expression.aspx

Thanks for the reply

I am still struggling though. The cloumn I am calling is a calculated column. What data type does this come under. I have tried using the convert function but have had no success as of yet.

Thanks

I'm afraid I don't know. I'm not really an expert with the UDT module, I just know enough to interface with it for the UDT Data Source. You should try asking this question in the UDT forums.

Hope that helps!
