Hi,
The reason for the error is exactly as Gary stated in his response above.

Because the second part of your IF statement checks for a value of
"intRecordCount > 1" I would guess that the "+" (which you can use for
adding numbers in C#) should probably be "&&" (which means AND). If this is
the case then the first part of the IF statement also needs to give a
boolean answer (True or False) and not purely a number. For example the
first part could read "int.Parse(intCurrIndex.Text) > 0" (greater than zero)
or "int.Parse(intCurrIndex.Text) != 0" (not equal zero). So, changing the
first part of the IF statement to return a boolean and the "+" to a "&&"
will remove the error, but you'll need to check if it provides you with the
expected result.

It really does depend what the code is trying to do, but hopefully this
helps.
