A commercial leased was signed in Florida. Now, the managing company and I are in dispute of what is the Base Rent amount.
 I was told verbally and by emailed confirmation that the space is 1,220 sqft. Base Rent will be $14/sqft  which is ($1,423/month) plus pro rated property taxes, cam, and insurance. 

I agreed to this and we signed a leasing agreement to those terms.   
 

The following is the RENT/SECURITY DEPOSIT section of my contract.   
  

RENT/SECURITY DEPOSIT: During the first year of the Term, Lessee shall pay Lessor monthly rental payments of $1,780.00, which such rate is based upon $14.00 per square foot ("Base Rent"), plus applicable sales tax, in addition to Lessee's proportionate share of common area maintenance ("CAM"), all payable in advance on the first day of the month ( collectively, the Base Rent, sales tax, CAM, property insurance, the "Rent"). Lessee shall pay the amount of $1,000 upon execution of this lease as security deposit (the Security Deposit).     
  

So to my surprise when it's time to pay the rent, I was told to pay more than $2000 and not the $1,780. I asked them what is the $1,780 mean and what about the $14 per square foot as base rent in the contract?

 They told me that the $1,780 is only the Base Rent and they made a mistake listing $14.00 per square foot  in the contract.

 I did my own calculation that if the base rent is $14/sqft +sales tax+Cam+insurance, then that number is $1781, very close to the $1,780.   

  
I want to fight this Base Rent that they are charging me. Moving forward, what should I do? Any advice would help, thank you for reading.
