Within a current load statement I would like to use the same calculated (concatenated value) again within the same load statement

My code..

Load

'param1:' & param1 & ';param2:' & param2  as   MyCalcField,

if (  MyCalcField =  'param1:test;param2... )

whereas the variable Calcfield shoud be the same as previous defined. However this code results in an error

Any ideas would be appreciated.
