.rdlc table use of SUM and SWITCH together?

Hello everyone, thanks in advance for reading. I'm new to reports and have tried searching for my answer with no luck. Any direction would be great.

Here is the issue, I have 3 colums in the dataset which display String data ("High", "Medium", or "Low")

I've added a column to the table on the report where I would like to convert the value of "High", "Medium" and "Low" to 3,2,1 respectively then SUM these numbers.

Is this possible? I've tried several variations of the code below--maybe it's not possible to do what I want? Thanks again for your time and help.

Fields!PP.Value is set to:

=Switch(Fields!Avail_Rank.Value = "High", 3, Fields!Avail_Rank.Value = "Medium", 2, Fields!Avail_Rank.Value = "Low", 1)

=Switch(Fields!Volume.Value = "High", 3, Fields!Volume.Value = "Medium", 2, Fields!Volume.Value = "Low", 1)

=Switch(Fields!Integ_Rank.Value = "High", 3, Fields!Integ_Rank.Value = "Medium", 2, Fields!Integ_Rank.Value = "Low", 1)

=Sum(Fields!Avail_Rank.Value + Fields!Volume.Value + Fields!Integ_Rank)

One way of doing this is to define calculated fields on your dataset.

For example, define a calculated field called Avail_Rank_Numeric with the value expression: =Switch(Fields!Avail_Rank.Value = "High", 3, Fields!Avail_Rank.Value = "Medium", 2, Fields!Avail_Rank.Value = "Low", 1)

Then, in the Sum aggregate function in the report body use it as follows:
=Sum(Fields!Avail_Rank_Numeric.Value + ...)
