You need to document (or you have already documented)preferably with law enforcement witnessing denial of ordered visitation specifically on the dates on which visitation is supposed to happen.
That is the evidence you will use to prove to the court that you attempted to exercise visitation rights. This website has the forms:

12.960 Motion for Civil Contempt/Enforcement
Fill it out, take it the courthouse, have it notarized, you will pay a fee to have it served on the custodial parent or her attorney.
Here is where to see what the statute says re. visitation rights and penalties:

Scroll down to chapter 61.13. Good luck
(4)(a) When a noncustodial parent who is ordered to pay child support or alimony and who is awarded visitation rights fails to pay child support or alimony, the custodial parent shall not refuse to honor the noncustodial parent's visitation rights.
(b) When a custodial parent refuses to honor a noncustodial parent's visitation rights, the noncustodial parent shall not fail to pay any ordered child support or alimony.
(c) When a custodial parent refuses to honor a noncustodial parent's or grandparent's visitation rights without proper cause, the court shall, after calculating the amount of visitation improperly denied, award the noncustodial parent or grandparent a sufficient amount of extra visitation to compensate the noncustodial parent or grandparent, which visitation shall be ordered as expeditiously as possible in a manner consistent with the best interests of the child and scheduled in a manner that is convenient for the person deprived of visitation. In ordering any makeup visitation, the court shall schedule such visitation in a manner that is consistent with the best interests of the child or children and that is convenient for the noncustodial parent or grandparent. In addition, the court:
1. May order the custodial parent to pay reasonable court costs and attorney's fees incurred by the noncustodial parent or grandparent to enforce their visitation rights or make up improperly denied visitation;
2. May order the custodial parent to attend the parenting course approved by the judicial circuit;
3. May order the custodial parent to do community service if the order will not interfere with the welfare of the child;
4. May order the custodial parent to have the financial burden of promoting frequent and continuing contact when the custodial parent and child reside further than 60 miles from the noncustodial parent;
5. May award custody, rotating custody, or primary residence to the noncustodial parent, upon the request of the noncustodial parent, if the award is in the best interests of the child; or
6. May impose any other reasonable sanction as a result of noncompliance.
(d) A person who violates this subsection may be punished by contempt of court or other remedies as the court deems appropriate.
(5) The court may make specific orders for the care and custody of the minor child as from the circumstances of the parties and the nature of the case is equitable and provide for child support in accordance with the guidelines in s. 61.30. An award of shared parental responsibility of a minor child does not preclude the court from entering an order for child support of the child.
