Bash variable losing value

I recently added a variable to a script process that will be used as a replacement value via sed for an output script (not bash). This is one of many variables set within an if statement and (for reasons I cannot seem to deduce) the variable loses its value once outside of the if statement. This is not occurring with any of the other variables that are set within the if statement. Code and expanded results follow. if [ ${ModeTyp} == "P" ] ; then PC_DB=idpacleanelig PS2_DB=idpaprodserv2 PV_DB=idpaprodviews PV_OUT=idpaprodviews P_DB=idpaprod P_DBIN=idpaprod CERNH="CE_RunHierarchyControl_T" | CECONTROL=CE_LegacyControlTable_RHMv5 echo "CERNH value is ${CERNH} after Default Population in if prod statement" else PC_DB=hfsdevsandbox PS2_DB=hfsdevsandbox PV_DB=idpaprodviews PV_OUT=hfsdevsandbox P_DB=hfsdevsandbox P_DBIN=idpaprod CERNH="CE_RunHierarchyControl_T" | CECONTROL=CE_LegacyControlTable_RHMv5 GOTOLBL_1="" GOTOLBL_3="" echo "CERNH value is ${CERNH} after Default Population in if test statement" fi echo "CERNH value is ${CERNH} after Default Population" RUN RESULTS: + '[' T == P ']' + PC_DB=hfsdevsandbox + PS2_DB=hfsdevsandbox + PV_DB=idpaprodviews + PV_OUT=hfsdevsandbox + P_DB=hfsdevsandbox + P_DBIN=idpaprod + CECONTROL=CE_LegacyControlTable_RHMv5 + CERNH=CE_RunHierarchyControl_T + GOTOLBL_1= + GOTOLBL_3= + echo 'CERNH value is CE_RunHierarchyControl_T after Default Population in if test statement' CERNH value is CE_RunHierarchyControl_T after Default Population in if test statement + echo 'CERNH value is after Default Population' CERNH value is after Default Population
