SECTION LABELS , MIX UP OF BOTH SLOPES AND PERCENTAGES

[chasm9a252523]

I am new to Autocad Civil 3d and i am using autocad civil 3d 2012.

I am trying to label my sections through SEGMENT LABELS.

My output will involve both percent grades and slopes but i am getting result shown below

86275

However i want result in this style.

86276

I have came up with a solution and it seems to be working except one part.

I have declared an expression like this one.
IF({Section Segment Cross Slope}<-0.05|{Section Segment Cross Slope}>0.05, 1: {Section Segment Elevation Change}/{Section Segment Slope Length},{Section Segment Cross Slope})

In this expression, i cannot represent "1:" in the label style. This must be only text. If i write it as "1:" then it gives me an error.

or alternately

IF({Section Segment Cross Slope}<-0.05|{Section Segment Cross Slope}>0.05, "< I want this space to be blank, that is not represented by anything >",{Section Segment Cross Slope})

My main point is that i want to involve some text in my expressions and i dont know how to do it. CAN IT BE DONE?

Thanks in advance.

As far as I know, strings are not allowed in expressions.
