Big Problem

[adm1973]

Plz i wont to know what is the wrong in this statement
Dim SQL as string
SQL = "update TBL_TEST_LIB set FEES='" & "' ,fees'" - AdjustAmount.Text & "'"

CN.Execute SQL

[DataMiser]

Assuming Fees is numeric in your DB then pretty much everything after the =

[HanneSThEGreaT]

Need way more info. What are you trying to do?

[WoF]

The setting of quotes seems completely wrong to me.
Assuming fees is numeric and you want to subtract the value in AdjyustAmount.Text then I'd say it should look like:

SQL = "update TBL_TEST_LIB set FEES= & (fees - Val(AdjustAmount.Text) & ";"

[firoz.raj]

Try the following way !

dim SQL$
SQL = "update TBL_TEST_LIB set FEES=" & (fees - Val(AdjustAmount.Text) 
CN.Execute SQL

[DataMiser]

It is possible guys that Fees is not a variable within the program but rather the intent may be to reduce the current value of Fees in the database by the value of the text in the text box. In which case the select would need to be a bit different than any posted thus far.

The op needs to provide info as to what he is actually trying to do.

[firoz.raj]

if fees is either integer or Long Variable then the following code will work fine .let me know .really what you want ? .

dim SQL$
SQL = "update TBL_TEST_LIB set FEES=" & (fees - Val(AdjustAmount.Text) 
CN.Execute SQL

[WoF]

Oh. Seems I forgot a quote in my first answer.
Ok, if DataMisers assumption is right and we want to reduce a field named FEES by a value then it must be:

SQL = "update TBL_TEST_LIB set FEES=FEES & " - " & AdjustAmount.Text

where the text field must contain a valid numerical.

[firoz.raj]

HI Wof,
it seems one more Inverted Comma is Needed .isn't it ?

SQL = "update TBL_TEST_LIB set FEES=" FEES & " - " & AdjustAmount.Text

[WoF]

Oh... I forgot to delete the first & and following quote.
Yes, firoz, it obviously is. But NOT in the place you are indicating.
My final vote is

SQL = "update TBL_TEST_LIB set FEES=FEES - " & AdjustAmount.Text

FEES is a field name of the table. It is not known stand-alone outside the SQL string.
The only thing outside the string which must be catenated with the & is the numeric value in the text field. Even the Minus sign must be within the string.

The only thing outside the string which must be catenated with the & is the numeric value in the text field. Even the Minus sign must be within the string.

oh yes, wof is really genious .i even did not notice . fees is a fieldName in a table TBL_TEST_LIB .

[DataMiser]

oh yes, wof is really genious .i even did not notice . fees is a fieldName in a table TBL_TEST_LIB .

That is what I was talking about in Post #6

The code posted by WOF is probably what he needs but since the OP did not explain what he was trying to do it is not possible to be sure.

[WoF]

We could produce some more proposals while waiting for a reply of the OP.
