Run time error 20515

Run Time error '20515'
Error in formula <CM_OPN_AMT>.
'IF {@OpnBal} = '0' THEN ({Temp_Clnt_PrvAmt.CMAmt}) - ({Temp_Clnt_PrvAmt.Amt_Rcvd})'
A number is required here.

Formula i am using is

IF {@OpnBal} = '0' THEN ({Temp_Clnt_PrvAmt.CMAmt}) - ({Temp_Clnt_PrvAmt.Amt_Rcvd})

Please help.

Try

IF {@OpnBal} = 0 THEN ({Temp_Clnt_PrvAmt.CMAmt}) - ({Temp_Clnt_PrvAmt.Amt_Rcvd})

Are the other fields numbers or strings?

getting OpnBal value from vb form

prvOpnBal = Val(Rs2Clnt.Fields(0)) - Val(Rs2Clnt.Fields(1))
CrystalReport1.Formulas(5) = "OpnBal = '" & prvOpnBal & "'"

What is OpnBal in the report?
Since you replace it, the replacement is causing the problem

You say the error is in this formula

IF {@OpnBal} = '0' THEN ({Temp_Clnt_PrvAmt.CMAmt}) - ({Temp_Clnt_PrvAmt.Amt_Rcvd})

Need to know if that formula is part of the report or the formula you are changing from code?

If it is not the formula you are changing then what is the original formula?

as far as i tried with different different ways
now

///trying to add Sum ({CLNT_Ledger.CMAmt}, {CLNT_Ledger.conName}) in @OpnBal
formula for CM_OPN_AMT is

IF {@OpnBal} = '0' THEN Sum ({CLNT_Ledger.CMAmt}, {CLNT_Ledger.conName}) else
({@OpnBal}) + Sum ({CLNT_Ledger.CMAmt}, {CLNT_Ledger.conName})

it says string is required here cursor shows between + and Sum

mlmccCommented:
OpnBal is apparently a string value.

Is it a formula or a parameter?

Try

Simplifying this to

Val({@OpnBal}) + Sum ({CLNT_Ledger.CMAmt}, {CLNT_Ledger.conName})

If OpnBal = '0' then the Value is 0 and doesn't change the sum
