I am having to pull a cost from a string....
 substr(l.details, instr(l.details , ':' ) +1)AS charge,

This works for doing the calculations correctly, HOWEVER when I to print the value is prints as an 'object'  not a string.

I have tried cast and convert....how can i get this above code to print the actual string out

Try

Cast (substr(l.details, instr(l.details , ':' ) +1), varchar(5))

or whatever size you need

That gave me an error at the ,

I did cast to a double but it created it as a zero.

The value I am looking to see is .70

First make sure the extraction gets you the value out.
Can you post the string from which you want the data extracted?

Declare @vCostString as varchar(50)

Set @vCostString = 'This is the cost :1.07';

Select Cast(substring(@vCostString, charindex(':',@vCostString) +1, 4) as varchar(5))

I guessed at lenght of 4 which is 1.07 value lenght.

We need a string example to make formula as you expect

Maybe this sample select is enough to get you started
