I am working a bug and during project creation if the user selects a Large Sto

Hi
Any insight on the below issue which we have facing on our project will be helpful. I am working on a bug and during project creation if the user selects a Large Store, Convenience Retail or Drug Value originating channel the selection of project subtype should be an optional (not required) selection. The dropdown selection should not be removed.
Could anyone let me know what could be the logic which I should use so that" Project Subtype"should be optional for Large Store, Convenience Retail or Drug Value originating channel .
We are using an expression rule "prmOrigChanHasProjectSubType" to pick the originating channel from the constant used out in this expression. PRM_ORIG_CHAN_STORE_LG = Large Store
=if(contains({cons!PRM_ORIG_CHAN_REGION, cons!PRM_ORIG_CHAN_STORE_LG, cons!PRM_ORIG_CHAN_CONV_RETAIL, cons!PRM_ORIG_CHAN_DRUG_VALUE, cons!PRM_ORIG_CHAN_CANADA, cons!PRM_ORIG_CHAN_OTHER}, ri!origChannel), true(), false()).
Then we have used " prmGetProjectProjectSubType" to returns the updated value of Project SubType based on originating channel info.
=if(rule!prmOrigChanHasProjectSubType(ri!origChannel), if(isNull(ri!origChannelSubType), "N/A", ri!origChannelSubType), "N/A")
We have used this express "prmListOrigChanSubTypeByOrigChan" to returns a list of channel sub types by originating channel.
=if(ri!origChannel=cons!PRM_ORIG_CHAN_REGION, rule!prmListOrigChanSubTypeRegion(),
if(ri!origChannel=cons!PRM_ORIG_CHAN_STORE_LG, rule!prmListOrigChanSubTypeStoreLG(),
if(ri!origChannel=cons!PRM_ORIG_CHAN_CONV_RETAIL, rule!prmListOrigChanSubTypeConvRetail(),
if(ri!origChannel=cons!PRM_ORIG_CHAN_DRUG_VALUE, rule!prmListOrigChanSubTypeDrugValue(),
if(ri!origChannel=cons!PRM_ORIG_CHAN_CANADA, rule!prmListOrigChanSubTypeCanada(),
if(ri!origChannel=cons!PRM_ORIG_CHAN_OTHER, rule!prmListOrigChanSubTypeOther(), ri!origChannelSubTypes))))))
Finally we have used this expression rule "prmListOrigChanSubTypeStoreLG" to list of originating channel subtypes for Large Store.
Could anyone let me know what could be the logic and in which expression rule which I should use so that" Project Subtype"should be optional for Large Store, Convenience Retail or Drug Value originating channel .
