Hi,
Can somebody help me resolve my problem ?
I am getting error when calculating total using unbound textfiled in subform.
I have a main form called purchase_register_master and a subform called purchase_register_details, In sub form i have a unbound textfield called txt_Total_Amount where in i am calculating total amount for different items purchased by giving following code in control source.
ContolSource: =Sum([Amount])
In my main form i have one more unbound text field named txt_Sub_Total
with the controlsource value as.
controlSource : =[Purchase_Register_Details].[Form]![txt_Total_Amount]
but i am getting error, i am not able to make out where is the mistake.
Can anybody help me in this regard?
Thanks and Regards
Sumit
