Showing error field : Flt AttrValue incorrect type for field conflicts with storage

 

If i remove Type then its showing "Credit"

 

[Field: IFLT AttrValue] ;;; its Default Field

Use : Short Name Field
Width : 10
Inactive : NOT $$IsEmpty:$SecondaryObject OR ($$Line > 1 AND $$IsEnd:#IFLTCombine) OR NOT $$Table:IFLTAttr:$NeedsParm
Storage : Attribute Value

Where to change?

 

Now in filter its showing 0.00 , Amount not fetch

Code:

[#Field            :    EBanking Summary CrAmount]
Type            :    Amount
Modifies        :    LastReconAmt    :    Yes

[Variable         :     LastReconAmt]
Type              :     Amount
Persistent         :     Yes

[System            :     Variable]
LastReconAmt:   :""

[#Field            :     IFLT AttrValue];;;i want to showing amount in this field
Type            :    String
Set as            :    ##LastReconAmt
Set Always        :    Yes
On                 :    Focus    :    yes    :    Set Field    :    ##LastReconAmt
