Error converting data type varchar to float. when trying to run stored procedure

When I try and run the stored procedure below, it is breaking on line 67. I believe this is caused by the following line:

set @sqlCmd = @sqlCmd + ' Cast(SUM(tbl_Cogs.MwhAct * (tbl_Cogs.BalMarkPrem + ' + @BalMarkPrem + ')) / SUM(tbl_Cogs.MwhAct) as Dec(8,3) ) AS WABalMarkPrem, '

This is the error that I am getting:

Msg 8114, Level 16, State 5, Procedure ShowCogsDetail, Line 67

Hello utlonghornjulie,

The data type of the parameter/variable @BalMarkPrem is most likely float and so SQL sees the + which should be concatenting that value to your dynamic SQL string as addition of two floats however the string with SQL statements can't be converted to float since they are T-SQL and not numbers.  To fix, you must cast the paramater to varchar so that SQL knows to concatenate as string.

sqlCmd = @sqlCmd + ' Cast(SUM(tbl_Cogs.MwhAct * (tbl_Cogs.BalMarkPrem + ' + CAST(@BalMarkPrem AS VARCHAR(20)) + ')) / SUM(tbl_Cogs.MwhAct) as Dec(8,3) ) AS WABalMarkPrem, '

Best regards,
